Opening PDFs - Anyone else experiencing issues with File columns suddenly not able to open PDFs?

Just wondering if anyone else is having issues opening files in the app for generated PDFs? A process I have had in place for over a year suddenly stopped working. All file names were mysteriously blanked out. Refreshing them allowed users to see the file for a few moments but then we get a “File not found” message.

Anyone else seeing odd behavior with PDF File columns and ability to view associated files?

I guess no one else is having this difficulty. I have implemented an alternative solution using Virtual Columns but would rather not keep it permanent since it impacts Sync times which I am trying to reduce.
