Have you had trouble playing animations lately? (Patreon)

H! guys, lately some people have reported problems to me when they try to reproduce the animations, so I would like to do a survey to find out what the scope of this problem is.

I recently found a video compression method that offers the highest possible quality in terms of colors, bit depth, etc, but this seems to be causing some players to not be able to play the videos, especially when it comes to playing from a smartphone.
