My wife and I both have K-9 on Android 11 set up with SMTP to our gmail accounts. Recently emails from gmail addresses to each of our gmail accounts have not been downloading to either of our K-9 apps even though they show up on our gmail accounts.
I don’t know if this is a google problem or a K-9 problem.
I tried posting on Github as an issue, but it was closed telling me to post in support.
