Recent 14.8 update has broken Messaging
I recently upgraded my iPhone (12), my iPad (Pro 12”), Watch (6) and MacBook Pro (2013 - to Big Sur 11.6) as per the advice given.
I now can no longer send messages (SMS and MMS) to non-Apple users. IMessage is working absolutely fine, and while I’m all for Apple having world domination, there are some of my family and friends who don’t see it this way.
It is not my wireless connection, it is not my service provider. All was working fine across the four devices until I installed the upgrade.
I have tried all the - totally useless - suggestions that I have been able to Google.
iPhone 12 Pro Max, iOS 14
