[OBSOLETE] differences between "SmartThings Classic" (the V2 app) and “SmartThings (Samsung Connect)” (the V3 app)

As of this writing, the iOS version of the new V3 app needs to have the Geopresence used for the phone location refreshed from time to time. This seems like it is probably a bug, but it has now persisted through several updates to the app, so maybe not. With the classic app, it is the android version which is more likely to need location refreshed.
