Had one iPad that would crash out every time it tried to connect to the DL32R. Tried everything - uninstalling and reloading the app, rebooting, etc.
The solution was to use another device that was having no problem, and to change a few settings, save the show, reload the show and then try on the other iPad.
So, if anyone has a glitch this weekend, try that. I emailed Mackie support with details. Surely some show corruption there.
