Can’t move email messages to folders
I have 3 email accounts on my iPhone 12. I have always been able to move messages from the inbox of each account to folders within the same account using the little folder icon at the bottom of the screen. In the last few days I have been unable to move messages, and when I touch the icon it says ‘move this message to a new mailbox’. I do not want to move messages to a new mailbox, I just want the icon to do what it did before. I don’t understand what has changed. Can anyone help?
