Message download stalls on MacOS
I'm running Thunderbird 78.14.0 on MacOS 11.6
Frequently Thunderbird on my Macbook will 'stall' when trying to refresh the inbox for my Google mail account (google worksplace).
If I switch folders, the the newly selected folder will download.
If I switch to a few other folders, and back to the inbox, the inbox folder will refresh.
When I switch folders, I see the status bar showing sending login & refreshing contents. The folders that don't download do not show the status bar updates.
I'm almost certain it's a setting that I inadvertently tweaked, but can't figure out which one.
