I was recently told by a tour coming through our house of another house with an SQ series mixer with a faulty encoder and i instantly asked why not switch the encoder in the soft rotary assign tab.
I was surprised to learn and not see an option for this as a soft rotary assignment, as this one rotary is mission critical and if it goes down the only option is the app.
This should be an important upgrade feature - Not that I have heard about this happening often, but on tour it could be a serious issue.
