On July 09th I got a K-9 update; on July 10th I got the OUI update 8.0 on Android 16. K-9 is not working anymore; a restart didn´t solve the problem.
Anybody wanting to help you will need more than just “not working”. What exactly isn’t working?
Did you check all your email accounts in K-9 and make sure incoming/outgoing servers are correct, and that all the folders are too? Did you try removing + re-adding one of the email accounts?
Thanks for the quick reply. It seemed to be a coincidence that whilst the mentioned updates accrued the provider had also run a system update.
Everything is working now.
