You didn't mention the plugin, so whitelist it and restart your watch and phone and see if things work@Dante63 the moto g7 is not rooted. The sync with the watch and samsung health worked for about a day.
All of the apps are listed as "not optimized" under the battery settings in each app's info. That's galaxy watch4 manager, galaxy wearable, and samsung health.
@73sydney I am simply using the play store version of samsung health, 6.21.2.007
