In the “Channel Settings” page (the three vertical buttons on the top right corner of the “Channel Info” page), there is a “Play” button for you to change “Top to Bottom” or “Bottom to Top”, which will change the playback order, not the order of the episode list. For example, there are 3 episodes in a channel, you select “Bottom to Top”, playback will start from the 3rd episode and continue to the 2nd episode.
