Can't fetch products from App Store connect

I had everything working with Revenue Cat. Then my app got rejected for not loading subscriptions, which was odd because a previous built was rejected for wording on that same paywall.

I checked, and realised I suddenly can't fetch products in testFlight either. I can only see products in Xcode using the store kit configuration file.

I've found many issues like this online and everybody point to the same solutions (that seem to work for most), but here's what I tried so far:

1. Checked that all my agreements in App Store Connect are active
2. Checked that ids match between Xcode / revenue cat / App Store connect
3. Store kit config file is syncing with App Store Connect correctly
4. I removed revenue cat and used the store kit api directly to fetch products. The array of products is empty in all environments that don't have access to store kit config file.
5. Checked status of all subscriptions (all waiting for review -- as they were when the paywall worked)

Nothing seems to work...

Any suggestions? Many thanks
