For us, it kept disabling the application (first time, it said it was out of date). But we also have a git pull setup that syncs between servers, so the app needed to be staged and then pushed live. After we uninstalled and reinstalled yesterday it is still active, so I have adjusted the settings today from the default again to fully expand.
However, I still don't really understand what the "Allow these groups to change settings" does, because I can't find anything in Account settings that allows people to adjust the way quotes work for them.
