I have tried at least 3 watchfaces that have an Altimeter feature but none of them grabbed any altitude information. I have a Gear S3 and a Galaxy S8+. I have gone into Permissions on Facer and enabled all three buttons but somehow when I back out of the settings and go back into Permissions all but the Location buttons went back to the Off position. Any suggestions?
In answer to my own inquiry I found that deleting Facer from my Gear S3 and reinstalling it solved the problem.
