Been using this app for years and it's always been really good. However for the last week I have been unable to send nor receive emails. I have tried deleting a load of emails and even folders, in case it was too full, have tried logging out and back in again, checked my internet connection and abilities to connect to other things, which proves my internet connection is fine and have tried everything else I can think of to try, but the problem persists. Please help Developers!
