Exporting files in mobile

We have a responsive page that exports a list into .csv format. For mobile view, what is the optimal way of going about it?

Show the user a notice that exporting is only supported in desktop?

One initial idea was to hide "Export" button in mobile view, however, Android actually does support file downloading. It may not also be a good idea to do browser detection and hide the button only in Safari. Seems like it's not a scalable solution.
