Hi Danny and the Fly Delta Android team. I've been using the Fly Delta app for a few months on my Nexus S phone, and just started having trouble after Google pushed the upgrade to Android 4.0.3 to my phone over the air (actually, they recommended using WiFi because of the update's size) a couple of weeks ago. This is with Fly Delta 1.6.
Problem 1: Fly Delta doesn't allow me to check in for a flight anymore. I am offered all the choices for checking in up until the final screen. I can get as far as the Select Bags screen. On the Select Bags screen, I can successfully select the option "Select or Change Seats". However, the "Check In Now" button doesn't work - when I touch and hold the button, I can see the color of the button changes, but nothing else happens - I'm stuck at this point and cannot proceed to get a boarding pass.
Problem 2: When displaying the seat map, the seat icons are much larger than prior to the Android 4.0.3 update. For example, on my current flight in first class on a 757-300 aircraft, when the seat map is displayed, I can only see down to a part of row 2 vertically, and horizontally, the only seats I can see are A and B - I have to scroll to the right to see C and D. It's as if the screen is zoomed by pressing + several times but the - option is greyed out so that's as small as the seat map gets. On an economy seat map - also for a 757-300, the screen starts with rows 14-16 and is cut off on the right hand side with half of seat E visible.
