— They could have just sat on it for 3 weeks then did the review yesterday.
If they tested your in app purchases three weeks ago then it would make no sense why others were failing it at the same time. As I said previously I have used the exact same build for both iOS, Google Play and Amazon with the same common CocoonJS IAP events. iOS doesnt work the rest do. So unless I have to do something special for iOS (i.e. iOS Shared Secret key) then I'll assume that Ludei have fixed the backend and they reviewed your app this week.
Anyway, I'll resubmit my app shortly and let you know the outcome.
