I have hthe playpad pro as well, its been over a month since its release and the playground app is virtually useless. It only allows keyboard mapping and remapping HID buttons. Futhermore, in HID mode, only 1 stick and the top two triggers along with the face buttons are recognized by most apps. To get all the buttons in emulators and games, you have to use the playground app. Pairing is a pain too, you can't use playground with a pre-paired controller, it must be removed and done from the playground app. Kind of a ****ty implementation, but hey, its beta still right? Im really hoping for an update, the controller form factor is mint, and the sticks are 360 style, making it an awesome gamepad for mobile. As of now, its kind of junk...
