Yes, the IGATIWBWEASI!
Which was followed by what may have looked to some like the lab scene from The Andromeda Strain. I told a friend how I cleaned them / tested them that they were actually cleaned and he just said "that's so you" 😐
The one side thing actually happens more often with my Pros (mix of 1/2nd gen, mostly still 1st), I've almost never had it happen with the Airpods (all third gen in my case) - " " fortunately " " it doesn't happen that often and even then usually happens while marathoning two APPs during multiple run-on Teams meetings (I do this with Airpods too but I can't remember the last time I experienced one-sidedness), so I just live with it connecting on one side - then when the meetings are finally over I make the case do PacMan things and fish the earphones in and out and it usually resolves the problem.
The Mute/Unmute shows up constantly across the board and as I mentioned above, I just ignore it.
