I'm having the same problem with Part XX of the ITA (I'm in Canada). I've been in compliance for days, everything in an active state, but app store connect says I'm not, so I can't bundle subscriptions/in-app purchases in my app, which means I can't submit it.

That helps confirm that it's probably an internal glitch on Apple's part. Hopefully they read these forums. I have a phone call scheduled.

The tax error went away. Thanks for dealing with that! But i'm still unable to add in-app purchases or subscriptions to my build.

That is, the option isn't even presented. See the attached screenshot. It should be between Build and Game Center, I believe.

Just to make it clear: The In-App Purchases and Subscriptions section appears in the left sidebar under Monetization, but it does not appear in the main content area of the version page between Build and Game Center. I cannot attach my subscriptions to the build for submission. I've tried multiple browsers and uploaded a new build, but the section still won't render. I'm forced to conclude it's an Apple backend issue.

Having the exact same issue and have tried every workaround imaginable, doing everything the OP said. Been going on for days. Please help!!

I'm having the same issue, but for some reason I'm getting rejected b/c it says no subscriptinos area attached.

I’ve done all of this and it’s still not working.

Did it. Here's the ticket number: FB22421220
