Bugs in content types

Hi, I try to import mp4 tutorials in a course presentation but received this message (invalid security token). Do you have any idea of the problem ?

Thanks   Jacky

Hi Guys,

Since upgrading, I've noted that some elements do not show on mobile/ tablets. For example in the attached file there are two interactive presentations missing. They show up fine on desktop (both Chrome and Safari).

In addition, the memory game doesn't function properly. When clicked, and the option is the incorrect one, it remains open. Users can't play that game from their mobile. The actual page is here: trinikidscorner.com/mothers-day

Any suggestions on how to fix these would be appreciated.

Regards,

TKC
