@arman-g This appears to be an issue with Adaptive Cards - not Web Chat. I’ve opened an issue in the Adaptive Cards Repo and you can track the progress of the issue here. Thanks for reporting the issue!

@corinagum The Mock Bot Video command is a video card. This issue is related to videos in Adaptive Cards. I’m working on trying to repro the issue outside the scope of Web Chat to see if it’s an issue with Adaptive Cards.
