Don't attempt to implement Dynamic Type (larger text) on iPhone/iPad.
If Large Text is selected (via Settings/General/Accessability) this is poorly implemented on OneDrive, eg folder names beneath the folder icon (Files view). People with visual disabilities can Zoom the whole page. As mentioned elsewhere when folders are displayed with a sliver of a photo please can this be enlarged as per oneDrive v9.9 (v10 is a setback).
I would like to be able to see the thumbnails
