This app worked *until* I paid for it. – Momego - Live transit tracker Review

So, I was using this with no issues, and I thought purchasing the premium package to remove ads would be a win - both for myself and for the developers. Haven't been able to use the app at all since then, despite multiple OS upgrades and re-installing the predecessor app. (By this, I mean the app opens and immediately crashes. It's literally impossible to get a worse deal out of a purchase.) I'm leaving this review here until the developers patch the bug or refund me. I advise that nobody pay for an upgrade in the meantime.
