This is the closest thread I could find for this:
Task bar hover controls (pause, next back) appear not to work during video adverts (obviously next/back don't anyway)
the Hover control will show that it is either paused or playing, however the advert continues to play.
The main window controls do control the advert fine, and will display the actual state (playing/paused)
This seems to only occurr with video adverts, and is fine with audio adverts. (the only video tested with is the national trust one)
Closing due to inactivity. If you need more help, please submit a new issue.
Thanks for taking the time to do a search first. I've created a new Open Issue for you here, now.
