Unable to display emails
My email setup was operating fine so far. A couple of days ago, I could see the number of emails in the Springboard, but nothing was displaying when opening up incoming email accounts. Settings have not been touched. Tried rebooting, hard reset, delete and create accounts from scratch, all with no success. You can see an example in the picture of incoming account below (sorry for the language, it's in Greek). Any suggestions please?
