No training load counted after watch reboot itself

I had a similar experience last week. My 970 rebooted after a bike ride into a nearby village to run a 5 km race. When I ended the bike ride my rebooted, and I didn't think very much about it. I ran my race and all seemed fine.

But back home some data wasn't measured anymore. On my 970 I noticed that the VO2MAX graph was gone, and Connect didn't showed trainigstatus anymore. I tried several things (switching off the 970, logging out from my Connect account), but in the end I restored the Forerunner, and all the missing data was back in Connect.

It took me a lot of time to configure the 970 again. I had to connect all my sensors again.

Succes Frank

it happened again today on rebooted and lost some data on software 6.18

im losing my patience already

I had this happen twice on version 6.18 — the lack of a significant amount of data really messed up my stats on Connect. I'm trying to sort it out with support, but so far it doesn't look promising.
Hopefully, this won't show up in the beta.

This happened to me yesterday as well. Load, status, running tolerance and endurance all reset despite having many activities

anyone else with issues?

U need to restart the watch after it reboot itself. Then it will start to count again. That is the temporary solution. If it reboot again, turn the device off and on again
