Cancel a running/finished Ad for reloading scene

Hello I have my app set so if its on background more than 10 minutes I reload the scene but here is the problem. If I do this:

  1. Watch ad and let it finish (without closing it)
  2. Send the app to background
  3. Wait 10 min
  4. Bring back app

Result:
The finished AD is still in screen while the scene is being reloaded… I dont wan’t this I want to kill the AD somehow so the loading screen can be seen while reloading.

Any help?
Thanks

I still would like to know what to do here, I guess it’s not possible to kill the AD window for safety measures maybe?
