Thanks @DTS Engineer. It turned out that you need to push a new commit in order for Xcode Cloud to recognise an existing branch. Not sure if this is expected behaviour but not the best experience after changing the repository. I would expect all the branches to be listed :)

@ziggmike Does changing the prefix not reset the data for existing apps though?

While on this topic, will it become available in production this fall?

@allyLuna ah yes that would be the reason! StoreKit configuration is only for testing in the local environment, so you will need to use sandbox

@hsc101 no worries - glad it helped! :)

@allyLuna Unfortunately I'm not familiar with Objective C but below is the Swift equivalent. Have you tried leaving options empty or nil? let receiptData = try? Data(contentsOf: receiptUrl).base64EncodedString()

It worked for a while, but started happening again. Not sure if it's a separate issue. https://developer.apple.com/forums/thread/760548
