I have been unable to set up multiple phones to integrate a single Schlage Encode into the Ring App. I set my phone up just fine, but I am the “owner” of the Schlage account. I have others set up as admins but they integrations won’t work. Note this requires the use of Amazon Key which will only allow the “owner” of the lock to integrate.
This may be user error but i’m 5 days into trying to figure this out and just warning you in case this is something you want to do.
