I agree that mine is also working "the way it was before last week" but I can't say it's working "correctly." (No offense intended, friend.) It has never been "correct" in my opinion because all 3 speeds have never been "right". Speed 1 was OK, speed 2 wasn't reasonably quicker and then speed 3 has always been way, way, WAY, **WAY** too fast. It seems as if the 3 speeds are relative to the length of the entire video. In other words, if you're watching a 40 minute TV show, the 3rd speed is maybe somewhat too fast. But if you bought a movie with a few hours of additional, extra features, the 3rd speed may advance at 30 minutes per second on the 3rd level of fast forward and that's just *WAY* too unusable fast.
After reading so many comments here I'm now wondering if I'm complaining in the right place. Is this a Roku App problem or is it an Amazon Prime App problem. Where should I really direct my complaint/suggestion?
