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

[xRuby]

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

Hier hetzelfde probleem!

As others have said, it eventually syncs the next day, sometimes hours after the activity.  Hopefully we get a real fix soon.  With the current instructions that you provided, will uninstalling/reinstalling the app on our watch cause past activities to be erased?  Or will only activities that have not been synced get erased?

This is still not sorted. I'm still having problems after a week

Same issue as rest; Galaxy watch 5 / Samsung S21 Ultra. Also noticed that it synced approx half a day later. Suggested steps by mod haven't worked :(. Fingers crossed for a fix soon !

Issue was fixed via the suggested option (turning on and off both smartphone and watch) but had the same issue with my next run.

Also, as the app on the watch tries to sunc continuously, it is draining the battery life.

Please provide a sustainable solution.

Same issue with Galaxy Watch 4 and Samsung Note 10+.  Samsung pushed an update on the Galaxy watch a few weeks ago, and ever since then, it's like the Strava app is absolutely unable to sync.  How hard can it be to sync data between a phone and a watch?? I'm paying premium membership for what here?

Hi All, 
Sorry for the continued trouble. Our team has noted that the following may resolve the issue; please give this a try: 

1. Ensure that your Watch and Strava app on the watch are up to date
    
2. Restart your Watch, and your phone, if attempting to sync through bluetooth
    
3. Make sure your phone and watch have more than 25 percent battery life.
    
4. Make sure your watch does not have any modes on that restrict syncing:
   
   First, make sure your watch doesn't have Power saving, Airplane mode, or Watch only mode turned on. These modes restrict features that are required to sync data.
   
   Here's how to turn off these different settings:
   
   - Power saving mode: Swipe down from the top of the screen, and then tap the Power saving icon - it looks like a battery. Then, make sure the watch does not have a Power saving mode turned on.
   
   - Airplane mode: Swipe down from the top of the screen, and then swipe to and tap the Airplane icon.
   
   - Watch only mode: From Settings, swipe to and tap Battery, then tap Power mode, and then choose Standard. On the Galaxy Watch, press and hold the Power key to turn off the watch, and then press and hold the Power key again to turn it back on.
    
5. Make sure your phone and watch are connected through Bluetooth or your watch is connected to a strong wifi signal.

If this fails to push over the pending uploads then the app will need to be uninstalled/reinstalled and the activities will be lost as they are unable to be manually extracted from the device.

Hello,

Power mode / airplane mode / watch only mode were not activated. 

Power % was over 25 for both watch and phone.

Both watch and phone are updated, in fact there were no issues before the latest Samsung update to the Galaxy 4.

I rebooted both phone and watch, and I even uninstalled both apps.

The problem persisted. Last bike run only synced on its own after 4 hours - completely random. I've lost two activities in the past week because they would just not sync.

Dit is geen oplossing. Nu al dagen problemen. Het is niet meer leuk. Ben mooie activiteiten kwijt. Teleurgesteld in Strava!
