EU MOSS VAT declaration

I have an app where some authorized authors can write content, then the app users with a subscription can access this content.

I do not really know which part of VAT I will have to pay, my company is in UK and most of the customers are in France

In my mind I have this distribution, apple takes 30% of revenue, so I have €70 on this the company takes 20% and redistribute 80% to authors. so the company will have €14 and the author €56

On that each one will have to pay VAT so apple will do his own declaration and will pay VAT on €30, the company will do the same and pay VAT on €14 and the author pay VAT on €56

Please let me know if I am correct
