We are creating an app for turn-by-turn navigation in CarPlay. I would like to change the information displayed during navigation between Dashboard and others. I understand from Apple's documentation that this can be achieved by giving strings for both dashboardInstructionVariants and instructionVariants. However, when I actually try it, only the instructionVariants string is displayed. Is this a bug?

We are testing in-app purchases in a sandbox environment. In doing so, we encountered a problem with the "Interrupted Purchase" section. In the documentation, it says that "Interrupted Purchase" can be tested with steps 1-12. In fact, we can pass from 1 to 9, but at 10, we could not receive a new transaction of "SKPaymentTransactionState.purchased" in updatedTransactions. Is there something wrong with our app or sandbox environment? Best regards and thanks in advance.
