Infuse 8.2.1 has been approved and is now available on the App Store! 
This includes improved handling of purchases by way of StoreKit 2 which will allow Apple’s native Family Sharing to work on Apple TV when using multiple profiles.
We’ve also include additional improvements to allow Pro to be usable across all profiles on the same device even if they are not linked via Family Sharing (for example if you have multiple profiles linked to accounts in different App Store regions).
Thanks again for your patience and understanding.
