Bugs in content types

Hello

i have an issue about video’s submit screen.

when a user answers a single choice question (that exsists at the end of the video) but leaves the page before “sending the answer”,  the submit screen never pops up again for that user even if he watches the video again.

we can temporarily solve this with making little changes at the time of interactions and force user to restart the video activity. But this effects everyone…

Note: we prevent skipping forward at videos

Am I missing anything?  Is there a way to get the word search - Find the Words - to work on mobile?
