I’m having same notifications problems after upgrading to iOS 15.4 !! This is so annoying !! And phone gets very hot on iPhone 12 Pro Max

Did anyone find a solution?

I’ve tried everything online, turned off Bluetooth, restarted so on. Apple support has been very frustrating and has been no help what so ever - missing really important messages.

Thanks!!!

i am having the same problem. no notifications when iphone is locked, and no notifications on apple watch. this just started. i have tried all of the suggestions with no luck. apple, please help.

since I got my iPhone 12 in January I have not been getting half my Facebook notifications, instagram, or none of my mail notifications. Recently the past 2 days I have not been getting my Facebook messenger notifications. It’s very frustrating bc I’m missing very Important information and messages I need to read

this was driving me crazy!

I went into messages via settings and noticed in the area “allow messages to access”, “Focus” was toggled to on. I turned it off then texts notifications and ringtone worked. I then went to Focus via settings to find do not disturb was ticked then was turned on…. Not my doing, was done via update - thanks apple!! Hope this helps someone else.

So, today I decided to rest my iPhone and I was happy I did because then I started getting notifications for Facebook messenger again. However, about 15 mins ago, I stopped getting notified. Apple, please fix all notifications for all apps. Myself and others are missing important messages. It’s very frustrating since the iOS update. Ughhhh 😩😩😩

I'm having same problem. I checked every setting including Notifications, Do Not Disturb, Silent mode button, Message settings and Sound & Haptics to make sure notifications and sound levels were on. I even did a hard phone reboot. I have not "Reset All Settings" or "Erase All Content and Settings" since I don't want to lose my information and apps.

I think some of you said your problem started when you updated to iOS 15.4 but I'm on 14.8.1 and I have same problem. I'm using iPhone 12 Pro Max.

Good luck everyone, hope we get a fix soon!

Mine did as well, the missing notifications randomly started started in 14.8.1 but I thought if I update my phone then it would be fine. Alas I was wrong, and the issue carried into 15.4.

So far the only thing that has worked for me unfortunately was to delete all my apps and re-download. I backed everything through a program called iMazing so I can access all my back ups and messages - even export all the media and messages as a PDF. After I did that because I didn’t want to lose anything, I went ahead and deleted all my apps and re-downloaded.

It’s all working again. It’s so unfortunate that this is the route I have to take but I was missing urgent messages and I didn’t know what else to do.

Hopefully there’s a solution in the near future because this is ridiculous. Apple needs to get their sh*t together ASAP.

Best of luck - I know it’s insanely inconvenient but I hope this solution helps.

I bought Iphone 13promax 256gig (Alpine green) 15.4 version and I have issue about not getting notification when I am using data. If my phone was connected to wifi all apps are working fine and Im getting notification. I came from Iphone 7plus so I knew what is do’s and donts. I tried everything to fix the issue but it still not working.

Check Notifications > Scheduled Summary. This is new to this update and my Messages were grouped in with my other apps so it wasn't alerting for new messages. Either turn off scheduled summary or toggle off the Messages app from the list.

I have been having a similar problem, no notification tones for iMessages when phones are locked, for a few weeks for my iPhone 12 Pro Max and my wife's iPhone 8 Max, both running IOS 15.4.1. We get tones for SMS, but not iMessage. Message Notifications were always enabled. I tried several fixes found online to no avail. Since the problem was just with iMessage and not SMS, I decided to remove our cell numbers from iMessage and FaceTime and turned both off. We could then receive SMS from other iPhones (and Android phones) with a Notification tone. I then re-enabled our cell numbers/iMessage/FaceTime for our respective phones and now iMessage Notifications are working normally. I am not a programmer, but this appears to suggest a problem with iMessage/iCloud and not the iPhone or IOS, perhaps triggered by IOS updates. I hope this works for you.

Same issue since the past few IOS updates. Insta, whatsapp, gmail, calls. I am missing all the notifications. only when you open a particular app, you would know what you've missed since you don't even get notification number on the app icon.

VERY FRUSTRATING!!! I have missed imp calls and messages and I have to keep checking my phone a million times.

I'm having the same issue with a new phone. No notifications from anything except Gmail when the phone is locked. Sadder is that I've found posts about this issue dated a week ago. Shows that Apple thinks critical services like notifications of messages require no sense of urgency to fix.

I've tried every suggestion in this thread and many others from this forum and none of them have worked.

Same here. Both me and my wife have stopped getting notified about texts on our iPhones.

Got a text by my mother in law about my father in law going to the ER and my iPhone did not notify me. No one was happy about it.
