Screen just stops for no reason, seems to be buffering then an error message "unable to playback and it may get stuck in this cycle for an hour or more. Also may suddenly rewind a show your watching for absolutely no reason. Called customer service several times and gone through the same process over and over. Unplug the firestick, clear cache, reset your router, delete and reinstall Hulu, check your Internet speed, bla bla bla nothing works. We have one of the fastest Internet services in the nation in my area so that's not it.
