My app was denied because the 6.7" screenshots are outdated. But I can't find the 6.7" screenshots to update them. So I am stuck I can't update my app.
Where are 6.7" Screenshots
You can either use 6.7" or 6.9" screenshots in AppStoreConnect.
6.7" are provided by iPhone 15 Pro Max simulator for instance.
PS: Don't forget to close your threads when you got a solution, and let others know if and how the problem was solved.
