My iOS app (Flutter based) contains a file open dialog for several file types.
One function is to open GPX and KML map files. However, when I open the file selector I can see the files but I am not able to select them, they look disabled; when I tap on them, nothing happens.
Two things are strange:
- Another function must open image files. This is done with the same open file widget and works properly.
- We tested three different devices (2 different iPhones, 1 iPad). Only on my iPhone 11 Max is the problem. The other devices could open the GPX files without any problems.
So, I believe it depends on my specific device. I was looking for a specific permission which I can set somewhere in the settings but I was not able to solve the problem.
Does anybody has an idea why it is not possible to open the files?
Kind regards!
