I am running Samsung S8. Aqua Mail is the only email program I use and only 1 email account used in settings. Since recent updates, my app badge counter will show when I have a single message, but if I get any more emails, the badge counter disappears totally. In my drop down windowshade, it will show the correct number of new emails (ex. 6 unread emails), yet no badge matching it. This occurs whether I open app or not for the counter.
I have messed with the setting for ALL UNREAD & NEW UNREAD and get the same results.
Attaching screenshots, counter can be seen at bottom, then disappears when 2nd email comes in
