@jaron.davis I previously helped two people with what I believe is the exact same problem([here](https://devforum.zoom.us/t/issues-regarding-file-zoom-us/91878) and [here](https://devforum.zoom.us/t/issue-with-downloading-meeting-recording-transcript/135084)). The funny thing is: the second person I helped was named Jaron. It wasn’t you, was it?
