Thank you, this is what I need to see.
Our code already checks for com.lge.launcher2 and would find it
I can only guess that LG decided to do something differently on this particular device.
As I wrote above, this is an undocumented feature and only intended to be used by LG's (Samsung's, HTC's, Xiaomi's...) own software. This means we cannot get any info from LG on what's wrong and how to fix it.
Please consider using the app's widgets instead (they work on any phone) or maybe switch to a third party launcher (we support Nova Prime, Apex Pro, Smart Launcher where this feature is officially supported and documented).
