Doesn't Load

Used to be my go-to MBTA app, but now it won't load!

So much for those five bucks.

👎

I’ve had nothing but trouble getting the bus times to load the last two weeks. I’ve uninstall the app and all the troubleshooting things and still not working. Very frustrating because I need the app to get to work everyday.

App no longer updates times

Used this app for a long time, and now it no longer refreshes for me. Even after restarting. Please fix!

Often broken

The app often is just blank saying “no upcoming service” when they are always running. I end up just visiting websites anyways.

When it does work it is okay.
