Also if you want to do anything beyond “what the devs already thought about” you either need deep understanding of the specific system/app or rounds of trial and error. Case in point: tried sharing a vpn config with an Android user over Signal. They couldn’t do anything with the file, just yielding an error message saying it was unsupported. Sending the exact same file with a .pdf extension allowed them to download it and import it in their VPN app (only after downloading and installing a generic file manager app, though). Every now and then I struggle with some file that I can’t figure out how to move between apps. Something as seemingly simple as downloading an mp3 file from a browser and importing it to a music player app is quite an ordeal on iOS.
