Hi,
some of my users reported this problem today and I just finished simulating the scenario myself.
After firmware update 5.20 the the touch screen is entirely disabled when an activity session is started.
By entirely disabling I mean the menu won't open by pressing the center of the screen and the swipe and back gesture also stop working.
My code maps the events to the OnMenu, OnBack and OnSwipe.
After the problem manifests, the touchscreen is also disabled in the watch shortcuts menu (hold start key for 3 seconds)
Let me know if you need some additional information.
I will be glad to help.
Cheers,
Robinson
