iOS 15.4 notifications not working

I have been dealing for months with friends complaining about me not being notified of this message or that call. I checked notifications, focus, sounds, do not disturb....very frustrated. Finally today I decided to fix it. Googled. Found a lot of people having this problem. Tried this. Tried that. Finally...Reset all Setting. Lo and behold. Locked phone. Received text notification/sound. Went to set phone back up, custom sounds, wallpaper, etc. In Messages had to log back in with iCloud....notifications stopped working. WTH!? Remembered a post where a guy referenced iCloud breaking notifications. Logged out of iCloud...notifications work. Log back in. Nothing. Then remembered someone mentioned having to log out of messages on iPad. Was sitting at desk with my MacBookPro and AppleWatch on my arm. All latest hardware versions and iOS/MacOS versions. Noticed I WAS getting notifications on laptop. Closed laptop. Started getting notifications on watch but not phone. Took watch off. All the sudden phone is getting notifications. Reversed. Put watch on. No notifications on phone. On Watch. Opened laptop. No notifications on phone or watch...notification on laptop. Kind of cool but ultimately frustrating. Whether at work or home my laptop is almost always open. I have to conclude this is why I frequently am not notified of notifications when I'm in the next room. Apple needs to add a feature that allows you to either alert on all devices or set one as a "master" that always gets alerted or something. I hope this helps someone else who is dealing with this issue.

I was having the same issue the last couple days thought it was because I hadn’t updated yet. Updated and still had issue. Only thing that worked for me was logging out of iCloud and logging back in! Hope this helps someone!

So after reading these - I realized I am not the only one facing this issue. Either notifications on phone or watch ; not both. I am one of those ppl who would love both working back again to send notifications. If apple is really catering to people who want either or option then they should come up with a toggle button choice of both or one . Really frustrating to miss so many notifications .

Same **** issue! This is what Apple support is suggesting… I haven’t done it yet since don’t have access to a laptop ! “Ok, we can try to re update your device via iTunes. Your device is up to date, but re updating your device will force to install a new iOS “

Until Apple provides a solution for this issue, you can receive messages as SMS with a notification tone if you turn off iMessage on your iPhone. The message will not be forwarded to your iPad or Mac as it is with iMessage.

Just had this issue. Turned out I had “hide alerts” turned on for my favourite contacts - pretty sure an update did that not me! In the messages app, hold down on the favourite contact and make sure it says “hide alerts” (therefore meaning “show alerts” is activated. Swipe left on other non-favourite messages threads and click the bell.

hey, i was so scared that my family was gonna hate me for this being broken. luckily i found a fix, atleast for my situation i turned off notification grouping. somehow that affected how my messages appeared.

I've had the problem of no notifications for iMessages (I did receive notifications for SMS) for several months. I turned off iMessage and was able to receive notifications for SMS from iPhone users. I'm not sure if the problem is with iOS/iMessage or with the cellular provider interface (I use Xfinity Mobile). With the recent update to iOS 15.5 I continued to have the same problem until I went to Settings->Messages->iMessage-> Send & Receive and set the cell phone number as the ONLY Send & Receive option (NO email addresses). I am now receiving notifications for iMessage. This also worked for my wife's iPhone.

Hi, someone posted to go into settings because notifications was automatically turned off for txt. Sure enough this is what happened to my phone 11 after same update. Turned back on and all was good. Hope this works for you also.

Same with mine, battery runs down fast, and I can’t get notifications from my message app since I update to iOS 15.4, it’s so frustrating omg

Same issue for my updated iPhone 12 Pro and Apple Watch 4. Both updated to latest release and now having notification issues, specifically with iMessage.

Same here…I got a iPhone XS Max…after the update, I’ve missed a lot of texts, notifications, and my IMessage is giving me error as well

Same issue here on my wife’s phone. Did a settings reset, nothing.

iPhone 13 ProMax, iOS 15.4, focus not set, notifications on, nothing comes through.

I’ve been having the same issue for two days. None of suggestions online work. This is extremely frustrating
