Help, some mails are duplicate in the inbox. the "duplicate" is marked "older", no sender and no subject. but the content is the same as the "original".
if the "original" is deleted the "duplicate" is still present and has to be deleted separately.
if I delete the "duplicate" and leave the "original" in the inbox, the "duplicate" come back after a while.
Resetting the account removes "duplicates" but as soon new mails arrive new "duplicates" starts to appear.
Does anyone have a clue what this can be?
