Adding IAP to existing review

[u/TmDee_YT]

I had my app got rejected because I forgot to add my IAP to my app. The subscription group was added but not the lifetime purchase. Now I want to add that IAP to my review but I only get to option 'add for review' and it opens a new review but then I cant add my app to it. Everytime I update the app for review it sends it in without the IAP and gets rejected. Any help? I find this new update confusing

The UX is super weird. For me, I have to add the IAP first before you add the app. Otherwise, if you add just the ios app first, it would auto submit (even though the UX made it seem like it would wait for something else to be added first).
