I installed the Marrow app for viewing study lectures, but the audio and video becomes jerky when I change the video speed to 2x. Th app developer company Neuroglia says that it is a hardware issue some DRM or the like. Earlier when I was using my iPad, there was no problem. Now when I have migrated to a new Android Tab Samsung Gallaxy Tab A7, I am unable to use my education app Marrow. Please please help.
