Hello @Dazzler 

Thanks for posting about this.  Are you recording using the Strava Mobile App?  The first thing I would suggest is to ensure your App is updated to the latest version:

Google Play Store:

Strava: Track Running, Cycling & Swimming

How to update your apps on Android: Support - Google

Apple App Store:

Strava: Run, Ride, Swim

How to update your apps on Apple: Support - Apple

If that doesn't help, I would recommend you please submit a support ticket and someone from our Support Team will be happy to work with you directly to investigate what might be going on.   Thanks so much.

I have exactly the same issue, in the last few weeks, a total reset of my timer when doing weights. I wonder if a solution was found 

I have the same issue. Terribly frustrating. I also verified have the latest version. Any other fixes? 

Trying to record on the Strava app on the Google Pixel watch, never had an issue before today. The timer on the workout just resets to zero after a few seconds, doesn't record the calories burned. The app has been uninstalled from the watch and the phone, reinstalled and everything is up to date, and all permissions are allowed. What is the fix? This is very frustrating 

Same issue here. Have checked version and reinstalled 3 times to check....still doesn't work properly!
