Watch Activity Not Syncing to Phone

Hi!

The activity I do that registers in my Apple Watch (Series 5) has stopped syncing to my phone (11). It stopped properly syncing about a week ago.

Watch tracks and shows days of closed rings accurately, but Activity app in iPhone shows zero activity since it stopped syncing about a week ago.

Yesterday I completely un-paired/re-paired my watch to phone, but the issue persists. Not sure what else to do at this point.

Any ideas? Is there a setting somewhere in Settings, Watch or Activity I may have inadvertently turned off?

Thank you.
