If you are not the original owner of an account and do not know the POL mail password to access the mail delivered, the mail delivery notification does not go away and keeps flashing in game.
I have one account that I somehow was able to bypass the mail delivery check when a window popped up in POL which asked if it should quit checking mail. This account no longer has the mail delivery flashing.
I am hoping that someone here knows how to replicate what happened to me that one time, so I can get rid of the flashing on my other account.
Thank you for your assistance.
