yes I think i found the potential issue. The subscription status was not checked every time. It was based on cached old data. So even if you canceled it on the sandbox, you still would‘t see the upgrade screen that the reviewer was talking about. indirectly the rejection kind of found a bug. with the current inplementation users could cancel the subscription and still use the app like a paid member indefinitely

Thanks, I don't know if that's necessary, If someone from the review team has a couple of spare minutes that would be nice but it's ok either way, like I replied above I think I found the problem. Hopefully that is what the reviewer meant when they said they can't get to the subscribe screen and it's not something else. I have resubmited the app and we'll see if the issue is fixed once they reivew it again.
