John - I appreciate your continued development on this app. I’m having the same issue reported by multiple folks (mark2k, DrChops) above, re: presence sensor app detects me leaving my home WiFi network, but isn’t automatically notifying the server. With status and error messages turned on in the app, I see no notifications when connecting and disconnecting from WiFi. The location icon in Presence Sensor turns from blue to gray, so it seems like the app knows that I’m coming and going, but it isn’t automatically posting the activity. Using the manual refresh button in the app, I get the expected “Update successfully posted to server” notification. After using the manual refresh button everything seems to work fine for a while, and then the app reverts to the aforementioned unexpected behavior. I’m experiencing this issue on 3 android phones all running version 1.5 of the app on two different SmartThings locations. Let me know if I can forward any data to assist in working this issue. Thanks again for your help!
