Can’t change the row size in the basic grid view. The images are too small on iOS and can barely see them. Please allow adjusting the size of the row in the sme same way I can do that on the web or on the desktop app. The issue is in particular on iPad mini, it has high resolution but small screen. Very difficult to see what is on the image thumbnail.
That would be a nice feature. In the meantime, I would suggest using the gallery view on iOS.
