iPhone 12 not getting notifications

I was having the same issue. Open each app you want notifications from, you may need to sign in or authorize notifications. The apps I opened on my new phone started sending notifications. a couple I deleted the app and reinstalled and it worked.

I believe I have found the solution, at least from my iPhone 12… After you go to settings then notifications make sure that you exit out/delete notifications going to your former iPhone… When I went to notifications and scroll down a little bit I saw my iPhone XS was still the beneficiary of all of my notifications...Please let me know if this was helpful I hope so!

I had this issue on my iPhone 12 Pro Max since I got it last Friday and it was driving me nuts. I even tried the two public betas of iOS 14.3 to see if they fixed the issue (nope).

However, prompted by some comments on this forum, I changed some settings on my other phone on the same account and lo and behold, on now get notifications for iMessages on my new device.

Some detail: I have a work iPhone (an 8) which I have logged in to the same account as my personal phone (to access media, etc). Subsequently I can choose to receive messages to either number on either device. I had my personal phone set to only receive messages sent to my personal number/email and my work phone set to receive both work messages and personal ones. After removing the personal number from the work phone, my personal phone (the 12) suddenly started getting notifications/sounds for messages sent while locked (whereas previously it only worked if unlocked). It’s possible this might work with other devices on the same account (iPad etc) if set to receive on the same number as your iPhone 12. Not ideal, but worked for me.

I did the same when I transferred to my iPhone 12 from a 10s. I get all my notifications as long as my phone is not connected to anything Bluetooth. As soon as my phone connects to my Apple Watch it stops notifications coming to my phone. Turn blue tooth off and I get notifications again. No issues. But this is also happening on my wife’s iPhone 11 so it’s not a iPhone 12 issue it’s a software issue. Joke it’s not been sorted

The only option that has worked for me is turning wrist detection off on your watch. This way I get notifications on my phone and watch at same time. Only down side is I now need wrist detection on so I can unlock phone with mask. For me I will just use passcode code and leave wrist detection switched off

I had the same problem. All settings were the same as my old phone. After I opened each app and signed in if necessary, the notifications started showing up again

I don't understand why the Apple experts didn't just say: "You have to reload every application on your new IPhone AND log in to EVERY application to receive notifications."

If you have an Apple Watch, turn off Wrist Detection. Works for me!

If you have an Apple Watch, turn off Wrist Detection. Tried everything else before finding this. Works great!

So I don’t know if this has been covered or not, but I tried forgetting my wifi network on the new phone (I have the 12 mini) and rejoining and now my notifications are working.

I reset all my network settings and all notifications started working again.

It’s so unbelievable that we’re all having the same problem… I have no clue how I fixed my new iPhone 12 or Apple customer support did because I was on the phone with them, was able to see my previous phone under one of the settings and once I removed it I started getting notifications as normal and now my iPhone 12 is perfect… I suggest may be going to your Apple ID and removing old phones from it on the bottom.

One line answer--that's ALL you need to know. I saw the apps on my new phone but got no notifications. It took me a few hours to figure out how to make it work.

So why did Apple experts refer us to a page about how to set up the applications??

Set up my IPhone 12 Pro today and had the same issue - go to your WiFi settings and forget your WiFi network and reconnect to WiFi. That sorted out basics like texts, WhatsApp, email. Still not getting ones for certain apps so guess I’ll be carrying a couple of phones around ‘til I can sort them all 🤦🏼‍♀️

In case you didn't see my response to another post - try logging out and then back into those apps that require logins.

I'm trying to remember, but when I set up my new iPhone from backup I don't think I had to put in any passwords. So maybe all the logins on the new phone aren't 'valid'?
