I am not able to see my fitness tracking from my watch on my iPhone

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.

I’m having the same issue. My fitness tracking on my phone isn’t syncing with my Apple Watch. The phone is paired but not connected. I’ve tried restarting both phone and watch and unpairing and repairing. Neither helped. I have a IPhone 8+ and a Apple SE series.
