Updated to iOS 14 and now mail sends from wrong email address
I have a preferred email address in Apple Mail (which is an alias) and use three other aliases for subscriptions etc.
Since updating to iOS 14 on my iPhone 11 when I select my preferred alias for the From field, the emails are being sent from one of the other aliases - but I don't know this is happening until the email is sent.
I went in to preferences and disabled the alias Mail was choosing - and it duly elected the next alias. So I disabled that address too, and it picked another...
After disabling the 3 aliases my preferred alias email address was next up - only I use a .mac suffix and the iphone is choosing to send it with a .me suffix. And I can't disable that.
Basically I can no longer send emails from my iPhone unless I use an address I don't want to use.
No issue on my iPad (which is running 13.7) nor macbook. It's happened following iOs 14 update on my phone.
I haven't seen any other posts about this. I went onto Apple chat and after 1 hour of hanging on and making zero progress (the support people are clearly handling several users at the same time and all you see is that they're typing... just not to you).
Thanks
