My Streaming Stick (3600x - early 2017 model) has started stuttering/freezing video, but the audio keeps going. This is mainly on PSVue and on this unit only. Not seeing it on a Roku TV, Streaming Stick Plus or a new Streaming Stick (2018). I was getting power from the TV USB and thought that was a problem, and switched to the USB Adapter, not difference. It's running 9.0 (build 4084-24_ Internet speed is fine (65 MBps). Any thoughts?
