Real time map issues!

Real time map for route 15 does not work! Every time I try and open it, it shows a blank map with no route on it and then it immediately force closes. I take this route pretty much every day so that means I rely on the Marta app. Ive even asked someone else with the app to check the same route using real time map and it did the same thing for them. It also doesnt work for a few other routes that Ive tried checking. This problem had been going on for WEEKS and there still is no update to fix these issues.
