I’m using K9 Version 5.806 and Android Version 10 in a Motorola MotoG Power phone. I’m getting multiple notifications for each new mail received, always 2 but sometimes 3 or 4 per new mail. I am using the K9 to receive my Gmails using only one K9 account. My wife has the same multiples on her Samsung Galaxy A41 using exactly the same set-up for K9 as mine.
I’ve seen some old discussions for earlier versions of K9 but I am not using the Arlo app which has been suggested as a possible cause.
I’m currently using push, but the multiple notifications started before I started push. All suggestions will be gratefully received.
