AdService Issues (Using Android)

I’m using an Android device so AdService should be working, but it’s not. I’m also aware that AdService cannot be used on BC users.
Issues:
[ul]
[li]Sometimes the ads don’t show up at all[/li]
[li]VideoAdClosed fires even if the ad didn’t show up thus giving the player their free incentive[/li]
[li]Sometimes the screen goes black for 2 seconds then goes back to the game[/li]
[/ul]
I’m using Android 4.1.2 on SGH-1727 (Samsung Galaxy S2 Skyrocket)
I don’t expect it to work correctly on my phone because it’s pretty old but either way, we need a way to know that the ad successfully showed up otherwise we’re giving the player free stuff (if we’re offering items for watching ads)

I have a question too: do we still get our Robux if the ad doesn’t show up? (to be fair, we shouldn’t)

Don’t think we do get the revenue, my ad revenue plummeted in the past 2 days and I don’t think it was all iOS players since it reduced to about 10% for iOS ads being broken and recently it is at ~2% of original revenue.
