Same here mate.Yup it has issues, the apps you want edge lighting for have to be set to show popup notifications, not just regular notifications, so a lot of apps simply don't work. I can get it to work with a lot of apps when the screen is on, which kinda defeats the point. I got textra working as it has popup functionality and i had whatsapp working, but thats stopped working recently. Gave up in the end, couldn't be bothered with another gimmick that doesn't work properly.
