A folder link was shared with me. I can see the upload options but I receive an error immediately after attempting to upload a document. It says "There was an error uploading a file." If I click "Retry", it says "In queue..." and never uploads. I've tried uploading spreadsheets, PDFs, picture files (.png). I'm using Chrome and tried using Edge. No luck.
In fact, I cannot upload a screenshot of the errors to this message. It seems I'm unable to upload anything to this website.
