After lattest firmware update Elapsed and Total time are same are same. I had two stops but its not eliminated from total time. Please see attached activity pictures before and after firmware update.
Total time and Elapsed time being the same value indicates auto pause is switched off.
But auto pause is switched on
In that case it's not working as it should. If you've tried the first troubleshooting step of a reset, it might be best to contact Garmin Support.
