As representatives of the platform have already mentioned many times – limited tests of a given function do not mean that it will ever be implemented. However, it cannot be denied that the possibility of speeding up an episode or even a scene would sometimes be very useful.
The lucky ones report that the "Speed" option has appeared next to the button for changing the audio and subtitles. In menu you can reduce the speed to 0.5x or 0.75x or increase to 1.25x or 1.5x. There was no switch that allowed double-speed acceleration.
Personally, I am not in favor of maneuvering playback speed, but from conversations with friends I realize that this is quite a popular procedure. The function will certainly find its supporters also on Netflix, but at the moment it is not known if we will ever see it at all.
The possibility of accelerating or releasing the material on platforms other than Android has not been noticed, which suggests that we are dealing with a really early stage of testing new products.
