Support just told me there is no known issue, but my WEAR app and Watch (SM-R920) regularly resets this function to off. I reset it to on, and within hours it toggles itself back to off.
This also occurs with the "touch screen to wake" settings only less frequently.
How about any suggestions to keep the settings sticky? Samsung?
I would look at your apps and see which ones are using high amounts of data or battery. This will eliminate which apps. Also, setting 3rd party apps to no use Of background will fix this problem as well. It's best to just stick to Samsung apps in general, but if you can't, that is understandable. 3rd party apps can do a lot of damage or interfere in general with running your device.
Do you by any chance, have Sleep mode enabled at night in Modes and Routines on your phone? I do on my phone and it's set to disable Raise wrist to wake and Touch screen to wake on my watch during Sleep mode. Every once in a while it fails to change these two watch settings on or off. You should look through your Modes and Routines and see if anything there might be configured to change the settings on your watch.
