Sometimes it works and now last 2 days again no sync. 

There was an update in the google store but didn't solve the issue

+1 here now. Synced fine on Monday after run - now roll on to Wednesday it's not syncing at all. Is this bug getting fixed sometime as it's widespread?

I get the error on the Pixel Watch 2 (Strava App version 1.39, build 78101). The exact error message is this: 

Parameter specified as non-null is null: method yb.e.apply, para... [can't read the rest]

Same issue with Samsung watch 6 & Asus zenfone 8. I have 2 activates backed up both showing the same error. I have reset both phone and watch to no effect.

Hi, i solved the issue! 

Using samsung galaxy watch with samsung galaxy s22. I couldn't have resynced.

1. Try to restart both phone and your watch, and the error should dissalear.

2. Then wait overnight and resync - it should.

3. Uninstall application from both if your devices and reinstall them.

4. Resyncing shoukd work now right away.

(if you uninstall without syncing you will loose data. Thats why I'd try steps 1-2, before reinstalling)

I hope it will work for you!

Same issue here, I got the Null-parameter erro message and was unable to sync my run with the app. Pressing the sync button didn't do anything. Restarting the app, watch and smartphone app didn't do anything too. Got it resolved this morning by disabling the bluetooth on my phone en enabling it again.

Galaxy Watch 4 44mm and Pixel 6, both running all the latest updates

After a race, I got the same error. It was so frustrating because I PR and I couldn't see the full stats. After 8 hours, I hit the unsynced on the Strava app on the watch, it finally synced.
