I have been using both Life360 and the SmartThings app presence for some time with very few issues. By using both I kind of have dual detection.
My phone updated to Android 8 a couple months back. That didn’t change anything.
My wife’s phone updated to Android 8 about 3 weeks ago. Every since then her presence detection is about 5 minutes behind mine. I have checked all the settings, battery optimatization, location accuracy, etc. I have checked her location circles and they are as close to mine as I can get them.
This doesn’t appear to be a ST issue as Life360 is doing the same thing. Just wondered if anyone had any ideas.
