Ever since installing 15.4, iMessage repeatedly - deactivates, fails to activate and eventually reactivates with my phone number
Every since I installed 15.4 on both my iPhone and iPad, I've been having iMessage issues.
When I first installed the update, sometimes when I open my messages, all my received texts turn green. When I try to send a text, it doesn't go through. I turn off and on the phone and it goes back to normal.
Eventually I tried to fix it. I followed the following instructions from apple. I turned off iMessage and Facetime within my settings on my 13 pro and 2020 2nd gen ipad pro. I then restarted (turn on / off) the devices. When I reenabled the settings, iMessage and facetime failed to activate with my phone number. I waited 24 hours and eventually it reactivated. I am able to send messages via my number again. However, after a few hours, again it deactivates and defaults to my icloud email to send and receive messages. And then the above repeats itself.
Are any of you experiencing this after installing 15.4? I've never had any issues with iMessage before this.
