Extreme Portable is recognized by Windows, but not in iOS

Hey!

I have recently bought the SSD extreme portable and it works with windows fine, but with iOS( iphone), it doesn’t.

Other harddrives/SSDs are recognized in ios13’s files app, but the “extreme portable” isn’t.

I use the Apple USB Camera Adapter like many others. Most of hardrives work, but the extreme portable doesn’t.

Any ideas?
Does anyone know how one should solve this issue?

You are saying very true. I recently bought the SSD extreme portable and it works only for my windows computer when I started working with my Mac-book it won’t support.
