I'm having another problem with saving and loading on an Android smartphone. I had this problem a few years ago and now it's back again. When I test the app with "Run Application" on Windows, saving and loading an array file works. But nothing is saved on the Android smartphone. I have already tested whether the array is entered correctly and apparently that is not the problem. I always build my app with API 33.
Thanks for your help.
I have also attached a test file that works under Windows, but not on the phone.
