I've not been impressed with the Fire TV Plex app. The video stops playing every 3 minutes. I have a roku 3 and roku stick and never have the issues.

I use my phone as the remote - and so far so good. Edit: I should of noted that using Prime Video from the Fire Stick works perfectly (and it's faster to fast-forward etc than the roku).
