My opening screen events:

and I went into Admob and got the ad id not app id to use in the banner id setting for AdmobAds object in C3

You're missing a few steps.

Including the one where you pay for a subscription.

Every one carries on about the sub, not an issue for me, 1. I am part of the people who recently purchased so my first 12 months is covered and 2. Even if I wasn't I would still sub and try it for at least 1 sub period anyway.

3. Full access during the game jam. So please indicate where the sub was required

See the part that says beta?
