Threaded view keeps turning back on by itself
I am using version 115.5.1 of Thunderbird, all my folders are set to unthreaded view but Thunderbird will regularly turn one or several folders back to threaded view. When I say regularly I mean almost one time or more per 8 hours work day. I tried to identify a pattern, an action, a keyboard combination, anything really but I can't seem to find it. Today I literally just stepped away from my screen, came back 20 minutes later and found my folder in threaded view. It is driving me crazy.
How can I stop Thunderbird from forcing me to use this threaded view I do not want?
