Thank you for your continued support of Xiaomi products. The inability of certain third-party applications to function in landscape mode is primarily due to the application itself not being designed or optimized for this orientation. Some applications are developed specifically for portrait mode, and their interface does not dynamically adjust to landscape viewing. This is a limitation set by the application developers rather than the Xiaomi Pad 7. To ensure a smooth experience, it is recommended to use these third-party applications in portrait mode.
