iCloud Drive on my iPhone 15pro max

There is no option to swipe between documents either in the Files App on the iPhone or directly on the iCloud.com/drive website.

If you would like to see this, you can offer Apple feedback.

This isn't an iCloud thing; this is an app thing. Photos, for instance, allows you to swipe between image documents on an iPhone, but Preview doesn't let you swipe between image or pdf documents. You haven't said what sort of documents you might be talking about, or what app you might be trying to use. Perhaps you just need to find the right app.

I do find that if I tap to open an image that's on my iCloud Drive that I can swipe to the next image, and so on. It sort of works with other files, as well. Of course, most of the files in iCloud Drive are not kept locally in my phone's limited storage, so this sometimes requires a bit of a pause.
