Sudden problems with the app – Where's my MBTA Bus? Review

I’ve been using this app for 5 years and it has served me well. I’m sorry to have to write a poor review, but the in-all error reporting is not functioning. The time predictions seem to be accurate in the last 24 hours. But the GPS is not working at all. It shows locations that are inaccurate or no predictions at all, even when a bus is coming. Examples: last night on the 47, showed no predictions even though a bus was on its way. Today, gave a prediction of 3 minutes on the 64, which turned out to be correct. But the GPS showed the bus stuck in Union Square Allston, which is more than 10 minutes away. Tried to email about these problem but it said “email failed”. Please fix this app because I depend on it!
