Activity sharing not working at all

Apple can't expect the world to unpair and re-pair their phones.

They need to fix this ASAP

After I re-paired they are able to see my data. After they re-paired I am still unable to see their data update (shows as 0%). Restored from backup in both cases.

I took the advise of one of the posts and went thru the process un pairing and then pairing both my wife's and my apple watch again and now activity sharing works properly.

The whole reset took about an hour.

Update: Within a few hours of my friend repairing everything is working as it should.

I've done nothing and now after a couple of days my invitations are sending with no errors. Now let's see if my invitations are accepted and the sharing works.

So my mate accepted my invite. My watch shows his sharing data correctly but my phone shows 0%

Rebooted my phone and now all works. I think it's Apple servers. I did not pair/unpair my watch.

One thing I've noticed. If the other person has a different calorie goal the % comparision between you both becomes kind of pointless.

This solved the issue for me within 15 minutes of being repaired.

My friend re-paired his watch, now I can see his data. 🙂

Yes, I have the same problem. While Googling for a solution, I found this post suggesting that it was picked up during Beta, but never addressed: https://forums.developer.apple.com/thread/48880

In my case, no recover from backup. Simple apple watch unpair then pair back with the iPhone.

You need to be a little clearer in your terminology - what I think you mean is "unpairing" in the sense of briefly stopping Bluetooth on your iPhone. In that case, yes, it is a simple process.

However, there is another use of "unpair" from the Apple Watch app, which is a far more serious affair: your Watch is completely reset and the only way to get it working again is a "set up as new" or "restore from backup". For this, you need to set aside a good 40 minutes, and be prepared to go through the process of adding your credit/debit cards back to the Watch afterwards.

See my similar response below - do you mean unpair it in Bluetooth, or actually unpair the Watch from the iPhone?

One is a 60 second job... the other can take more than 60 minutes (it took me 20 minutes just now to complete unpairing).

True, I think I needed to be more clear. I tough all of us clearly discussed about the watch unpair/pair full procedure, not just the Bluetooth. The Bluetooth unpair/pair will only disconnect/connect locally and will most likely not solve the issue as it looks like the issue is more related to the iCloud sync. Try to do a Watch completely reset and then "set up as new" or "restore from backup". I suggest "restore from backup" so that you'll have it the way you had it before. This is what I did and it takes about 30 minutes (it varies based on each user content).

Unfortunately, unpairing and re-pairing with a restore didn't fix the issue. I can see my friends in the Activity app, but they're showing as 0%

I have exactly the same problem... the invitation is accepted, they can see my activity data, but I can't see theirs.

Both of us have tried rebooting devices, unsharing, re-sharing. I have tried a full unpair and re-pair of my Watch, restoring from backup. Last thing to try is for the other person to do that, but is this really the solution? Seems rather drastic, just to get a relatively trival feature to work.
