We had the same issue with an 3rd party library. Going to Build Settings and setting Validate Workspace to Yes solved it for us.

I can't see any situation we are pushing anything on top of Now Playing. The GridTemplate we only use as one of two templates in a TabBarTemplate. To set the Template we use either CPTabBarTemplate(templates: []) or tabBarTemplate.updateTemplates([gridTemplate, listTemplate]).

Thanks for this idea @fruitcoder_DE, I wasn't aware of this limitation of the stack in CarPlay. But unfortunately we have no case where we push a GridTemplate directly. We have just one place where a GridTemplate is used, and this is as one root template in a Tab template.

I've got the same problem. Error messages are only available in the Report Navigator (cmd + 9). Which is very uncomfortable to work with and features like "fix" or "fix all" don't work. Tried 14.0.0, 14.0.1 RC, 14.1 Beta 2+3.

There is a function in SoreKit AppStore.showManageSubscriptions(in: scene) this shows a list of Sandbox purchases. There you can also cancel and switch the subscriptions
