Error fetching offerings on device/testflight

ERROR: 🍎‼️ Error fetching offerings - The operation couldn’t be completed. (RevenueCat.OfferingsManager.Error error 1.)

There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from App Store Connect (or the StoreKit Configuration file if one is being used). 

More information: https://rev.cat/why-are-offerings-empty

and in app:

Error 23: There is an issue with your configuration. Check the underlying error for more details

Previously I’ve added a StoreKit Configuration file whilst working in simulators.

I still face the Error 23 issue in TestFlight as many of my testers have reported. I’m running my code on device, not simulator to try debug this, and have not selected a StoreKit config file in my schema. I have also tried deleting my StoreKit config file as well. My subscriptions and in app purchases have the status “Waiting for Review” in app store connect.
