Hi,
I had this issue not-long-ago. When the black screen appears please wait for about 2-3 seconds and then tap once on the screen (as if video is paused) and it starts. I do not know what this was from but not it is okay- I think that they will fix this with the time and also I am sure that until the end of the season you will watch your videos again and this will not be your last season (I hope so). Just have a little patience.
