The proposed solution of unchecking the column selection checkbox in IB attributes for the tableview does not solve it here ( macOS 12.4, Xcode 13.4.1 ). Maybe I'm too trusting but Xcode knows the column selection attribute is for a view-based tableview, so it could disable the Column checkbox to prevent the selection if it is truly not supported. The warning ( and whatever the underlying cause is ) has no visible impact on my app. Other workarounds and thoughts welcome ( TIA )!

Same issue here. Just want to test a MAS sandboxed app. This is Xcode 13.4.1 and macOS 12.4. I'd hoped the potential fix in macOS 12.2 solved it but apparently not. I really don't need StoreKit, so calling SKReceiptRefreshRequest isn't attractive unless no other workarounds appear. What is everyone doing?

Still don't know the cause but it was failing with the latest( 90.0.2) Firefox browser. The App Store allows access to the Agreements if the Safari browser is used.
