iOS11 notifications disappearing from lock screen

I just installed the new update 11.4.1 in the hopes this bug has been fixed but I’m sorry to report it has not. After the install I had my husband text me then waited a feeble more minutes and turned the phone back on. It showed 3 messages in the red dot notification but when I tapped on messages, of course they weren’t there and never will be.

I wonder, has anyone upgraded their iPhone and by so doing, gotten rid of the bug? I’m due for an upgrade but really don’t want to invest any more in Apple ifthat bug persists.

Can you please try to create a "sysdiagnose" file and in some way pass it on to me so I can add it to the bug report I've done with Apple? Instructions here:

I don’t have the problem myself and my friend who had it dropped his phone in the water before managing to create the log file. Now using a phone with iOS 10 he's not having the problem anymore.

Quick guide to create a ”sysdiagnose” file for those of you who are having the problem discussed in this thread. It's best if it can be done somewhat in conjunction with a messages disappearing, i.e. at most a few minutes after a messages has disappeared.

Do the following:

On the iPhone, press ”volume up”, ”volume down” and ”power button” simultaneously. This should trigger a short vibration on the iPhone. Wait a few minutes or so for the data to get collected (a sound can be heard when it's done), then go to ”Settings -> Privacy -> Analytics -> Analytics Data” and look for ”sysdiagnose” in the list and tap it (items should be sorted alphabetically).

In the upper right corner a share icon (square with an arrow pointing upwards) should be seen. Tap it and chose to send it as an email to me on staraffinity@gmail.com

I will attach the "sysdiagnose" file to a problem report I have done with Apple – hopefully this can help the engineers find the problem.

As I’m afraid to turn my phone off any more because of this isssue, I haven’t had any recurrences but I will stage some today and follow your directions and generate the report for you to send. I do very much appreciate your efforts in trying to solve this. Right now it’s the one thing keeping me from an upgrade to the 8 as it seems the problem persists with any upgrades. Thanks again. I hope you can get others to send you reports as well. Apple doesn’t seem the least bit interested in any problems these days. My Apple Pencil will not charge and they just said get the battery replaced at a Genius Bar. That means a 6 hour round trip for me when the guys at the Genius Bar admitted they don’t actually change the battery, they just give me a new pencil. The trip plus time and aggravation cost more than a new pencil so I will just have to buy one and hope it lastlonger than the first one. Thanks again.

This is the problem I am having too. Sometimes the notifications will remain all day until I get to them and sometimes they will all disappear after I acknowledge one or two. It is very inconsistent. Also I do not see an option to make notifications permanent or temporary so I can’t see that this is the problem. I use notifications like a to do list and get to them when I can but like I said sometimes they just disappear! What is the problem??

Ok update. I found how to make them temporary or persistent but that doesn’t explain why sometimes they are temporary and sometimes they are persistent especially considering that they were all set at temporary. It’s quite annoying.

I recently upgraded to OS 12, and thought I was seeing this behavior. Now it appears to have been ‘pilot error’. Under OS 10, using my iPhone 5, I would pick up the phone, and activate the screen with the home button. With OS 12 on an SE, I have ScreenAvtivate with Motion. If I go ahead and push home out of habit, the lock screen comes up, flushing notifications. If I do nothing, the screen activates and all notes are there for review. When/if I push home, they are dismissed, and the lock screen shows up.

So far, switching off "show in history" is working for me. I switched from a 6 plus to an 8 plus and they both had the same issue.

Settings > Notifications > Messages > Toggle "Show in History" off

This scrolls up and empty notifications with no clock. All is missing. I can reset but in a day or so it will go away again. This is rediculous.

I am having this issue too!

Thanks for the suggestion. I'll give it a try.

How do I "show off in history?"😐

Oh DUH! Thank you! And it’s fixed (for now)!
