Ah, thanks. That explains how you manage to have so many available. I like the progressive / adaptive mechanism as well, it keeps the challenge at the right level. Thanks for a great product.
There were some issues (crashes) with the videos on iPad, but I assume you’ve seen that in your logs already.
The iOS team doesn't see any recent crashes that associate to viewing videos.
If you want to follow up, feel free to email me your chess.com username and the approximate date when you had trouble; the team could look up crashes which happened to that username.
Both my personal and chess.com email addresses are in my profile.
