I thought I'd try the hotkey to watch face I'd set up (long press on LAP button) near the end of a run activity. In previous versions of the firmware, doing so disrupted the GPS logging.
The watch face came up and GPS stayed locked. That's good and an improvement on previous versions.
However, even though the activity continued in the background, the reminder to remove my Running Dynamics pod came up.
I dismissed it and was able to return to the activity the normal way (pressing Start).
