Lots of app problems. ON my Surface Duo it sops listing the APs when it reaches the fold in the screen. That’s minor.
The bigger problem is that “prepare device” has been failing most (correction, all) of the time. It managed to offer to update the bulb but still didn’t complete. How can I found out what is going wrong? It waits a long time and then says “try again”. And again and again and again and again.
