So version 4.21 comes out and Im able to update it on my iPad 2 (running ios 8), and a week later you release 4.22 to fix bugs but then make it only compatible with ios 9? Thats some forward thinking there for people who cant afford to upgrade their equipment, yet rely on public transit to get around. Sure, we can use 4.21, but as you admit by releasing 4.22 (a small step in version numbers) just to fix bugs, well have to rely on a buggy app to get us around. Great job, there....NOT!
