This is fun, congrats! The way you have the paywall set up keeps the user from experiencing the magic moment. Have you considered perhaps setting up a paywall that blocks the banner after 5 minutes, or one that removes branding from the banner?
We’ve decided to make more banners free, at least 2 per category, to allow users to toggle between the available banner designs.
A timeout feature or branding is a great idea, though. Thanks!
