RevenueCat - Getting this error consistently in Sandbox "There is a problem with the app store. Cannot connect to iTunes store"

Question

My RevenueCat integration was working in Sandbox for a week and suddenly stopped working with the error above. Its been broken for several days now and I am not sure if this is due to a config issue on my end or if Apple's sandbox is just broken. I am using the Flutter SDK.

I tried the following:

1. Created new sandbox accounts
2. Checked that all agreements and taxes are done (I see "Active" in the paid agreements section)
3. I checked to make sure that my subscription products were "Ready to submit" and were not missing any metadata
4. I created a new app in App Store connect and did everything from scratch.

Is there anything else I should try? See the image below for the experience.

Answer 1

I had the same problem, "Cannot connect to iTunes Store" (although without Revenue Cat). The solution was to update the test device to iOS 14.

Answer 2

It's a problem with the App Store /verifyReceipt endpoint affecting every developer, regardless of whether they're using RevenueCat or not. There's unfortunately nothing you can do.
