iPhone 15 Pro Max - Won't focus on small documents

I've been using Adobe Scan on my iPhone 11 Pro Max for several years with no issues.  When I want to scan a small document (e.g. 2" x 2"), I just hold the phone close to the document and all the fine print comes out crystal clear.  With the new iPhone 15 Pro Max, when I hold it close the image doesn't focus.  If I hold it far away (e.g. 12") to achieve focus, then manually zoom in on the screen, I can get a clean image but the text is fuzzy because its at the limit of the camera resolution (the text is only 1 or 2 mm high).  I've noticed that when just using the camera app by itself to take a picture of the same document, the camera appears to change lenses and a tulip icon appears in the lower left corner of the screen.  Is there a way for Adobe Scan to do the same?

Attached is a PDF showing the different scan results from the iPhone 11 and 15.

Thanks!
