There is an array of problems with this app. While it is good for my monthly pass and purchasing single rides on the go, it is frozen nearly every time I open it. Sometimes simply closing and reopening the app a bunch of times helps, sometimes I have to delete the app, redownload it, and enter all my information again. And if it does work, my favorites have likely disappeared.
