Email problems after update 13.1.2

After updating my iPhone 8 to version 13.1.2 I noticed that no new emails were arriving in my Inbox although my iPad had no such problems. I decided to delete the email account and to reinstall it to see if that fixed things. After going through the Add Account procedure I keep getting the message that the account already exists on my phone although I had deleted it and could not find it anywhere.

Any suggestions?
