Good morning @userhZc5g3rpth Try resetting your Galaxy Watch Active 2 after you've made sure you've backed up your data on the watch.
You can reset the watch two ways: the first through the Galaxy Wear app. Open the Galaxy Wear app> scroll down to "General" > then scroll down to "reset" then go through the process of resetting your Watch Active 2.
You can also reset your watch by pressing and holding the Power button which will boot you to the reboot menu menu> then scrolling the to the reset option there.
This should clear the issue both ways.
I have reset watch twice and no help...sorta upset with Samsung. Have never had an issue with my phones or any other product of theirs and when I try to set up a warranty return online it says something went wrong and to try again... well I have been trying and still nothing...
