Admob Ad banner

Hello,
I was using admob ads,the intersitial ones work perfectly fine but I don't understand that why the banner ad doesn't work in the extension. Can anyone guide me properly on how I can make the banner ad work? Thanks!

Stencyl now has built in support for Admobs and I've gotten the banner to work using those. You can find these blocks under "Game -> Mobile". I've gotten test ads to work fine by using only two blocks., "Initialize Admob ads (set banner position top)" and then "Show Admob banner". Works fine with test ads.
