I'm trying to create a submission with a subscription. I have already done this for an iOS application using a different subscription, and that is waiting review. When I try and do it for macOS I get the following error.
There is no additional information so how am I supposed to resolve this issue. I've tried removing both items and adding in different orders by I still get the same error.
I can't submit the macOS app by itself as it is rejected with needing a subscription alongside of it.
