2-sided marketplace/digital service/app store fee

My app enables dancers to monetize their work. Dances can be accessed through the app and learned with the features that we build (slow a video down, audio instructions).

The majority of the revenue goes to the dancer, as it is typical for 2-sided marketplaces, and the business takes a 10-20% cut.

Currently, we use IAP and users pay to unlock per dance. However, our business model is not feasible with the app store taking 15% and then 30% of the revenue in the long run.

  1. Are there exceptions for 2-sided marketplaces where the app store fee is being deducted from the business revenue, and not the overall revenue?

  2. If we have people purchase a subscription or credits on our website, what can we do to heighten our chances of that being approved by apple?

I know that reader apps are allowed to do that. The app should largely classify as a reader app, since the users access content through it, but we also offer some functionality (such as slowing down the video or using the camera), so I am worried that the app store is going to be difficult about this after we build the system.
