(RESOLVED) Error message (non-null is null) when attempting to sync activities on Wear OS app

[Former Member]

Sync of walk between Galaxy Watch 4 (Wear OS) and Samsung S21 failed. Fresh installs on both the phone and watch.

Honestly? For me it was my longest run ever and now it has to be discarded? There's no different approach to this? Really feeling reluctant to removing the application...

You could wait and try your chance tomorrow,  sometime I had 2 day without sync and the day after it synced.

All my synced now so I'll try the install uninstall

Same here.  I had a strong run yesterday and it wasn't sync'ing.  Somebody below mentioned to logout of Strava on the watch and then log back in again.  I just did it and it worked for me.  I'll now uninstall the app on the watch and reinstall.

Same here, I've just encountered the issue. So disappointed!

I got the same problem!! Which is the solution? 

[jonunverzagt]

Same problem here. Of course it had to be a PR too... let's go strava, you have been mostly flawless for years.  Why now? What changed? 

[TheDeanBE]

Still no fix? **bleep**, I have 5 exercises waiting to be uploaded.
Get your **bleep** together.

[chihhaochang]

Try logging out of Strava on the watch and log back in again.  This just worked for me.

Same, Galaxy Watch 6 - `parameter specified as non-null is null method yb.e.apply, parameter apierrors`

I'm having the same issue as well. Seems at random when the sync does go through. The fixes proposed by the Strava team do nothing for me sadly.

Seems this issue has been existing for more than a week now, this issue can be fixed by now surely.
