Trying to setup projectivy on new tv, but cant get passed usb debugging. Have tried disabling it but still won’t work. Any help appreciated.
Try using Launcher Manager along with Projectivy.
I have.
Not sure what kind of TV you have but I have a new Hisense and even though I have usb debugging turned on, it will not work. When I attempt to turn on wireless debugging, it just switches back to off. A little research informed me it’s a widely known bug on the Hisense firmware. 
New TCL QM8.
