So, the tutorial videos have been mostly pausing in the middle of the video, and it says something like this:
A network error caused the media download to fail part-way
with a giant X in the middle. At this point, I no longer can control the video, and the only thing I can do is to refresh. Since it is almost guaranteed to occur again, this could make a 15-minute lesson about 40ish minutes.
Hopefully, this is fixed soon because this is getting pretty annoying.
