I have been noticing a strange problem with notifications while using the beta versions.
I have two Samsung Android clients (Android 9 with One UI 1.0 and Android 10 with One UI 2.1) each with K-9 Mail version 5.913 configured with three POP3 email accounts.
I use Outlook under Windows as the primary email client which is used to compose and delete emails, the K-9 mail clients are mainly used to check emails while on the move and sometimes to send an email. Most interaction with K-9 Mail is to dismiss notifications by swiping right, I have noticed that many times (if not most) the dismissed notification reappears almost immediately and has to be dismissed a second time. I have been unable to identify the exact conditions for this to happen, just now I dismissed two notifications that occurred three hours ago without reappearing.
Has anybody else noticed this problem ?
