When installing Mobile Apps, the interface is automatically modified for phones or web, but the condition of determining which interface is ambiguous.
Interface for web is mainly used.
Install mobile apps for device implementing the Windows 10, and some of the interfaces are modified for phones.
Even though Windows 10 are implemented in all devices, different interfaces are automatically determined.
Therefore, it is such a troublesome.
It would be much better if interfaces can be user-selectable between phones and web by default, without device dependence.
