I am running MacOS Tahoe 26.1 on a MacBook Pro
For work, I often use the preview function in finder to type directly onto a PDF. I thought this was going fine -- the edits are saved and viewable in finder, even for people on other devices -- until I looked at the PDFs I've been editing on the web version of Dropbox. This is a problem in Safari, Chrome, and Firefox. The PDFs, other than the information scanned in the photocopier, are blank.
I have made sure to clear the dropbox cache, resinstall the dropbox app, restart my computer, verified that all my files are available offline and I have permission to edit them. Everything, according to the Dropbox app, is synced and up to date. What am I doing wrong?
