I like this app

Im using an iPhone 6 with the current iOS. It works great for me most of the time. Occasionally when I open the app to check in for my flight, it says that I need to use the kiosk at the airport. I shutdown the app (swipe up), then reopen, and it then it works fine.
It must be something with the latest operating system because it never did that before. I fly Southwest over 30 times a year and use this app frequently. I occasionally fly Delta, United, or American. I think this apps tops all of those.
