Doc, I am also using the Smartwatch 3 as my collector for my G5. It works better as the collector than my Huawei phone. Hope it will keep working when I change to G6 next week.
Is there a link somewhere to your settings in xDrip+ or do you have a list? I don’t understand some of them, and am not on Facebook so can’t access the help group.
I occasionally have to uninstall and reinstall xDrip+ when it stops working on the phone.
