BT email no longer loading on iPhone or iPad
I've always had 3 email accounts on my Apple devices - iCloud, gMail and BT Email, this has worked fine until just recently and now my BT email won't load on my devices. I get a message saying the log in details are incorrect, but I can log on just fine from my laptop. I did try deleting the account completely from my iPhone but now it won't even let me re add it.
Can anyone help?
iPhone 14 Pro Max, iOS 17
