Since the similar thread is 7 years old and it is not clear what a resolution can be, I dared to open a new one.
I have a vívomove Style device and Connect App for Android on Samsung S20 FE.
After finishing a Walk Activity with GPS on (~6km), I immediately synced my watch with Connect, but got a message similar to "Sync Complete, But It'll Take a While to Process". It's been 5 hours since then, and both in Connect App and on the web I cannot see any information on this activity. I can see the normal My Day metrics like steps, HR, but no Activity has been generated. Also, I checked the watch on the computer, there are no files in the ACTIVITY folder so I cannot do a manual upload.
I synced the watch a couple of times after, but still no luck. I tried making a short new walk activity with GPS on and when I saved it this got created very fast, without any issues in GC.
If I check the log of the Device Sync (see attached), it says successful.
I checked and the servers seem to be up .
Is there any way this would still show up? Can I do anything to try to retransfer it? I don't think it is on the watch anymore...
Thank you.
