For me it would crash immediately so I had no opportunity to log off.
After uninstalling, rebooting, reinstalling, rebooting, I did the following to get it going:
Put the phone into Airplane mode
Start SmartThings Mobile (which then complains about no internet)
Firstly, the new update is very welcome. It’s smoother and more refined. I did have to uninstall it and reinstall for it to work…no biggie. But, now I can’t change the color of any of my smart bulbs and light strips. I have some osram lights and lifx bulbs. Tried it on my android tablet and the color changed just fine, so it has to be the app. Anyone else?
I couldn’t get CoRE working with the older version of the windows phone mobile app nor the recent upgraded one. I have to edit the pistons on an android box too.
