Admob interstitials won't trigger with new extension {SOLVED}

Hi all,
I'm using the new Admob extension and I can't seem to be able to trigger the interstitials when a button is pressed, banners are fine though.  The Ad Unit id is correct, not sure why it won't load, anyone have any info or advice? I've attached an image with how I have it set up at the moment which should trigger interstitials.  many thanks!

You are using the blocks incorrect. In your case the interstial ad have no time to load. And it have to load first before it can be showed.

- Put the initialize block in "when created" in the first scene in your project (like in the load scene).
- leave the show block where it is right now.

Hi, thanks for your reply, the interstitials now work fine.  Thanks!
