Could the user permissions avoid that problem?

…SQ can have 10 other users, each with individual permissions, passwords,
scene access and user scenes (which are recalled on login).
This means multiple users can be logged in on different devices at the same time.
The Qu and our pad seem to follow each other so it seems like the SQ pad should change if the board changed.
Else one or both folks would not know what the settings really were.
With the multiple users for SQ there should be a way to keep them separate and not interfering.
Our answer was to tell our folks that only one person could access any given section and make changes.
You also should check what you are changing is what you want before you do it.
