Hello,
After latest app upgrade the widget stops working 
Before worked pretty good. Removing and adding widget didn’t resolve issue.
Yes, I can confirm…
Hello,
What mobile phone are you using, How much is the Android version?
Hello，
Is the widget does not display the device list？
or displays the list, but cannot control the status of the light？
There is no widget at all. I had it on my homescreen, after update it is empty (press to configure widget)… I am using Galaxy S8+, android 9
The issue was fixed, will release very soon. Thanks for your feedback.
LG G6 with Android 9 here.
Widget is available on list but after adding it on home screen it is filled by white background. Nothing else.
