JPG images uploading from my iPhone 11 to Dropbox as PDFs

[CarrieMarsh]

All of my JPG images in Dropbox on my laptop have converted to PDFs and are uploading as PDFs from my phone. On the Dropbox app on my phone the images are still JPGs. Can anyone tell me the setting to convert everything back and have my uploads remain in JPG format? Adobe won't even let me open the PDFS saying I have to upgrade to Pro!

Dropbox doesn't convert your files like that. Can you show some screenshots, before and after, of what you're seeing? Be sure to mask any private information.
