Hi, I can provide a bit more background information about that: 1) In order to restrict the available busses the app needs to load some sort of list which holds the busses the user should be able to select 2) Ideally this information should be stored on the mixer so you don't need to configure each tablet manually Since mixers are not designed to store these types of information (at least the currently supported mixers) Mixing Station is using the name of the last routing preset to store the bus + password that should be protected.
