Lost ability to save Lightroom Mobile for iPad edited images to Dropbox

[#1]

Apple replaced my 12.9" iPad Pro 2018 today because of defective RAM. When I re-installed Lightroom Mobile under iPadOS 13.2.3, I no longer can "save to files"  to my Dropbox. Formerly, when I wanted to "save to file" an edited raw image, LR automatically saved to a Dropbox folder.

Previously, Lightroom Mobile created a Dropbox folder "Uploads" and a sub-folder "Photos from LR Mobile" under which I could create sub-sub folders for different projects.

Now, my only save to file option is a hard drive (if one is connected) or iPad, although when I look at Dropbox from the Dropbox app, the folder structure and files saved before are all still there.

How to I get LR Mobile to save to that Dropbox "Photos from LR Mobile" folder (or any Dropbox folder) again?

Thanks!

First the simple stuff. Is dropbox installed on your iPad? Can you see dropbox in the Files app on your iPad and can you browse the folders on it? If those two work, you should be able to hite Save to Files in Lightroom, choose maximum available and in the next scfreen choose dropbox and the folder you want to put it in. If you've never opened the files app, it might not know about the dropbox connection.
