I have the galaxy smartwatch. I have a few new personal bests with running yet it won't update on Samsung health. I've checked my watch for updates and checked the app for updates. I've uninstalled and reinstalled Samsung health. I've tried deleting previous personal bests and now nothing appears for 5km run pb at all and my fastest pace hasn't updated, neither has my fastest 10km run.
My badges updates regularly though for sleep and that's up to date.
