Location only recognizes when SmartThings app open

[TmacDog (Timothy F MacDougall)]

I was having a problem after upgrading to iPhone 13, getting SmartThings to recognize the new phone as the prescence sensor. I fixed that but know it only works if SmartThings app is open. Any thoughts?

Iphone presence not working unless Smart-Things app left open all the time

Smart-Things has worked well for some time. Recently it stopped detecting mine and my wife’s iPhone reliably when we left or returned to the house. I verified that Smart-Things Location was set to Always. I finally discovered that it worked correctly as long as the app was open. Previously I could close the app as long as location was set to Always for Smart-Things. Any ideas ?
