IOS 14, iPhone 7 Plus Messages vanished
All my messages on iPhone 7 Plus have vanished after upgrading to iOS 14. iCloud was enabled for messages. When I sign out of Apple ID and login again, a message says there are no messages in iCloud as iCloud and iMessage accounts are different.
I asked my wife to message me. In her phone it shows delivered and I see it in notification but I do not receive it under messages.
I cannot send out a message. After composing. a message when I press the send button nothing happens.
What does it mean? How can I get back the messages.
