Problem (and steps to reproduce): If you let the video you’re watching buffer (in my case, a 20 minute anime episode) a considerable amount and then press ‘Rewind’ one time in an attempt to rewind the video 10 seconds, it will actually fast forward/skip up to the point which it has buffered to and then rewind 10 seconds from there.
Obviously, this is incredibly annoying. I’m sure it is a programming error of some sort, as I have been able to reproduce this on a reinstalled app. I hope my report can be of some use in solving this issue.
