Our iOS apps don't run properly after iOS 17.1.1 update. Our apps calls becomeFirstResponder when user taps on an editor button. And then it automaticalls calls the canBecomeFirstResponder command. In iOS 17.1.1 somehow the canBecomeFirstResponder gets called twice. As the variables and conditions are changed when the second call is made, everything gets messed up afterwards. Does anyone else have a similar issue? I'd appricaite it if someone can tell me this is an iOS bug that will be fixed, or if there is a workaround to fix this problem. Thanks.

Our apps, such as iCMTGIS PRO, provides the ability for users to open a job file received as an email attachment. Our apps use application:openurl:option to get the URL for the job file (*.pmp). We use [URL path] to convert it to NSString format. Then we use fopen to read the .pmp job file in "read only" mode. On iPad Air (5th generation) running iOS Version 18.6.2, our apps are able to read the .pmp job file. However, on iPhone 11 running iOS: 26.2, using fopen to read the .pmp file, we get a NULL value and are not able to correctly read the .pmp file.
