Files say “converting to pdf” but stuck on progress spinner for days

I am on Acrobat premium. Over the past year or so, I have converted hundreds of files to PDF (from Word, Powerpoint, etc). All of a sudden, recently, Acrobat hasn't been able to convert my files to PDF anymore. When I go to Adobe cloud storage, there is a list of my files, which all say "converting to pdf," but it never actually converts the files to PDFs. I see loading/progress spinners telling me to wait (photo attached). The loading/progress spinners have been spinning for several days now, but nothing happens. I tried restarting my ipad, but that hasn't resolved the issue.
