@Teemon: If you haven't done so already, please download the Galaxy Wearables app onto your S21 Ultra, and run through the set up. Now, in the Wearables app, go to Home > Notifications > On. Tap 'See All' under Recently Sent Notifications, tap the drop down arrow and select 'All'. Tap the switch next to any listed apps, and this should sync the notifications to your watch. I hope this helps.
