iOS11 notifications disappearing from lock screen

For me, it’s not consistent - definitely intermittent. Some message notifications appear fine, others don’t. I’ve not been able to identify any particular situation or set of conditions that triggers the behavior.

Sure - I’ll keep an eye out for it. I haven’t noticed any pattern in the past, in terms of it happening with certain conversations vs. others. And yes - I’m referring to routine notifications from the Messages app.

Here are 3 thoughts I’ve had.

1.) Just out of curiosity (I have NOT tried this yet), has anyone tried deleting the conversation history to see if that solves the problem? In other words, let’s say I fail to get a notification from Susie - one of my existing Messages conversations. If I delete the conversation for Susie, does the problem recur at some point with another message from her?

2.) Another idea. I have a scheduled Do Not Disturb period each day (7A to 10P). While this issue happens outside of that time window, is anyone experiencing this problem who does NOT have a daily scheduled DND period? Given the number of people who’ve joined this thread, I’m assuming this isn’t related but just wanted to throw that out there.

3.) And one last idea - a setting I just changed last week. In Settings / Messages / Audio Messages, I changed Expire After 2 Minutes to Expire Never. Yes - I’m clearly grasping at straws. :) It’s probably way too early to tell with any degree of confidence if this is somehow related, but I haven’t noticed the issue recur since I made that change.

Ironically, this just happened to me again now. I received a text message from a friend for whom I normally have no problems with notifications disappearing (at least, not that I can recall). At 11:26 local time, he sent me a text message - heard my phone buzz, but no notification message appeared on the lock screen. At 11:40, I unlocked the phone to check what happened. Messages badge app showed 1 new unread message. No notification message in my Notification History either. Also did a quick check of my MacBook Air and my iPad Pro, but neither device appeared to show receipt of the message yet. Just wanted to rule out the possibility that it somehow registered on one of those two devices. Both were locked at the time I received the message.

Anything else?

And obviously my idea regarding the audio messages expiration time made no difference - so I set that back to After 2 Minutes.

Haven’t seen the problem surface yet, but have only had a few texts come through since I updated my iOS yesterday. Will keep an eye on it and report back. I’ll be really frustrated if this hasn’t been fixed!

Well - that didn’t take long. :( NOT fixed for me with the 11.3 update. Just got a text message buzz - but no notification message on the lock screen at all. Exact same problem I’ve been experiencing. SO aggravating!!

Fail for me. :( I deleted ALL of my text conversations. Initial messages after the purge all came across with lock screen notifications just fine. One I just received, however, did NOT have a lock screen notification, so this fix did not work for me.

I've tried backup/restore as well. Heck, I've even tried it on another iPhone X.

One thing I haven't been able to do is try a clean install not restored from a previous backup. Too much history that I'm not willing to sacrifice (and Apple doesn't give us a way to import just text messages from a backup).

That makes it sound like it's a backend problem somewhere but what do I know… I haven't seen the problem and I use Messages (and other text services) with one iPhone, one iPad and two Macs. Wonder why it's only happening for some.

I guess you should be able to do something like that once Messages are stored in iCloud. The recently released iOS 11.4 beta seems to suggest it's coming when iOS 11.4 is done being in beta and released to the public.

This did not fix it.I am still having the issues after updates, 2 hours in the Apple Store & 4 calls at home this week & a complete restore to factory setting. For me, it is mostly texts from Android & if the phone has been turned off. Once I turn it on I may get a notification & once unlocked I can see that there are 1 or more messages but even that disappears in a second. I open up messages & nothing is there. Every time I get a call from Apple support they are like this is the first time they have heard of it!

Had the same problem with Apple. They always act as if they’ve never heard of this problem and then proceed to tell me it’s being fixed in the next iOS update. Somewhat contradictory at the least. That was three updates ago and still no fix. Lost count of how many full backups and restores I’ve had to do. There other manufacturers out there all competing for our business. Shame though. I love Apple products but this is just going in for far too long.

I would love to help with this issue as it’s become a constant source of aggravation in my world however I am denied access to the site for which you provided the link. Probably something to do with the fact that I live in Canada. It happens frequently. I wish you success though. I hope someday my expensive iPhone will again be as useful and reliable as it once was.

Oh, sorry – it seems one has to be logged in as a developer (or something) to access that PDF with the instructions. I’ll see if it’s possible to share in another way without violating any agreements.

I am having the same issue as others. However, I also totally “lost” the message being sent. It is simply gone from everywhere. As it turns out it is a very important message, and I do not have a return phone number! Any suggtions on how to find that message?

It seems the message is pretty much gone. I lost 3 yesterday & also do not have a return number. I am very angry that this has gone on for this long & Apple is not doing a **** thing about it. I cannot keep loosing/missing messages as I need it for my job & it is affecting my clients & my salary. Gonna go a get me an Android & be over Apple once & for all...

That’s the big problem. I can live with the notifications vanishing but the actual messages are lost forever too. There appears to be no way to retrieve them. I’m tired of the lack of interest Apple has shown in resolving this issue and I too am looking at Androids for my next upgrade. Good luck everyone.
