There is a new version of the app. Two of them going around but one is new and will save settings and also work with the 0-5v potentiometer for ebrake on the new controller setup only through usb and the new app that looks like the old, bluetooth and the old identical computer app will not save and refresh settings.
I found this out after frying 4 display and contacting mqcon to tell me I needed the new updated display and app because the old did not work with new settings.
New app can be downloaded directly from qs
