Hi,
The bug mentioned in the Alpha report is not resolved in the version 7.11
https://forums.garmin.com/beta-program/forerunner-945-lte/public-alpha-bug-reports/i/public-alpha-bug-reports/gps-off-when-return-to-watch-face-during-activity
In summary, when we go back to the watchface (example to see a widget), the activity loose the GPS and external ANT sensors (I don't know for Bluetooth sensors)
So you are loosing distance, speed, cadence, trace, ... during this time (it is restarting when you switch back to the activity)
Best regards gilles.k
P.S: It is certainly the same issue that we can see for the new 955 (but it was always working with my previous Garmin watches)
