Getting weird errors all of a sudden. It was not like this. I have been using this app a while and there's no issues until now. I need this work as it helps me to know wh at time the bus comes or if they cancel. I have tried uninstalling and then reinstalling the app but it's still give the same problem. If I can show you the error code it would be easier. It starts with "cert path validation exception" whatever that means. After that I can't pick any bus lines please fix app.

The app is decent, mostly accurate arrival times, tells you if a bus is canceled, next bus arrival times, etc. One consistent problem I've been experiencing is when I would switch to My Favorites, and it'd delete all my favorited bus stops. It happens once in a while but its very annoying as I have to manually type in and search each and every bus every time that happens.

update:Psyche! they added the very tinest piece of code to tells me that there is a problem, before crashing with a program halt. reboot, empty the data and cache try again... and crash again. are programs like this supposed to crash 99% of the time on a 2Gb Obama phone ( which most of the riders carry? ) 1.09Gb free after repotting several times. ( yes I have to check this every single time I use the app. it wants to own the WHOLE PHONE. )
