I have noticed that the iPhone presence is inconsistent - that is sometimes you have to open the smartthings app and “refresh” the mobile presence to get it to report presence. For example, I leave home and get to work - I notice my ‘away’ mode is not activated - then I notice my mobile presence still shows blue/present. If I pull-to-refresh the page that has my mobile presence, it will switch to showing me not present and then my away mode will activate.
This has happened to me about 4 times in the last two weeks. Anyone else seeing this?
