Long time, very happy K9 user on 4 or 5 phones. Decided to move from Pixel 3a to 4a, knowing that the 4a is new. Oops. After many install/uninstalls I managed to get one account working - at least it receives mail. The biggest problem and killer is the top-left/bottom-left back navigation arrows are missing. Makes navigation difficult. Also, forward nav buttons like “Next” sometimes don’t work.
Importing settings from previous phone: I put the k9s file in half a dozen folders but K9 didn’t see them when I navigated to them. I admit I don’t know exactly where to put the file. Have done it successfully on earlier phones.
Using version 5.600
