Hello!
My Yahoo inbox hasn’t updated since Oct 30th. I’ve been using K9 Mail for my Yahoo mailbox for a while before then, so my settings were correct. And I do have a GMail also checked by K9 which does successfully refresh.
I am running K9 Mail v6.202 on Android 12.
My Yahoo Fetch Incoming Server settings are imap.mail.yahoo.com, Port 993, with the Proper Username and Generated App Password.
I checked the K9 Log with Debugging turned on and found the segment below repeated a few times.
