I have consistently used auto-pause on rides (urban and trail) to great effect through multiple iterations of Apple Watch (series 6, Ultra, Ultra 2, Series 10) and versions of watchOS.  However about 3 months ago I noticed that auto-pause would stop with my first rest… and never resume.  This happened on my Ultra2, series 10 and now on my Ultra3.  This worked flawlessly for years… and now seems completely broken (I have not completed a ride successfully with auto-pause since the behavior started).  

I ride with just the watch (as I have always with no issue).   

Is anyone else experiencing this?
