NotAllowedError for MovieStim on mobile devices

Description of the problem:
Hi, I have been having trouble running various tasks on mobile devices as they have been raising ‘NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.’ when attempting to play videos. I have seen various threads about this but it is not clear if the issue was every adequately solved. Any guidance would be appreciated. Thank you
