iOS unable to save to Dropbox from Chrome or Safari

[RBiOS]

• When attempting to export a pdf file from iOS 12 iPad, Chrome or Safari the original file name changes to "file" followed my the month, day, hour, minute & second.  Have attempted from iPhone and problem does not occur.  Need the original name maintained during the exporting operation.

I have the same issue.  This is with an iPad.  In Safari, I can save the PDF to Dropbox.  In Chrome, I only have an option to save a file (that is not the PDF).

I solved it by opening Dropbox app. Turns out that Dropbox app just needs some updating.
