Well I fixed the issue, seems I can't have the setting in developer options enabled "do not keep activities" (destroy every activity as soon as the user leaves it). This setting turned on works fine with other home screen widgets, but doesn't like Poweramp. Turning it off made the widget appear properly.
Hello, I apologize if this has been covered, however I was unable to find anything myself - I have a Samsung Galaxy Note 3. When I try to add a Poweramp widget to a screen or page, it allows me to select which one, and configure it, however when I press ok it doesn't appear on the screen, only a message saying "press top right widget corner to reconfigure" I am not using third party widgets, only the ones that come with the program. Thanks
