Are you using the app when attempting to view the videos?
video lessons on mobile

yes, the video lesson button in the left hand corner.
I have also just checked and the video lessons are not loading on my computer (its the first time I have tried to use them)

sorry for the delay -- there' have been reports of a version of Chrome (v25) that is doing this. If you play videos on another browser, they should work. On your mobile this should work through the app.

Hi
I too upgraded my account for video lessons on my phone.
I also get the message "sorry, this video cannot be played".
I am using the phone app. I have a Samsung Galaxy 3.
Was there a solution found for this?
I would appreciate any help.

No despite emailing tech support several times and supplying info nothing has happened at all. I have given up. This is very disappointing
Part of the reason for joining chess.com was to watch video lessons on my phone. However all I get is "sorry, this video cannot be played".
I have an HTC wildfire, what do I need to to get the videos working.
