Zoom Recordings Randomly Do Not Download to Studio

[jfountain]

This has been an ongoing issue for us this academic year, even after rebuilding the Zoom Marketplace app required to transfer Zoom Cloud recordings to Studio.  I have re-opened the issue with both Zoom support and Instructure support.  I'm hoping our Canvas Community has the answer!

CURRENT SETUP

We have successfully configured 10 or so Canvas Studio accounts to automatically receive downloaded classroom recordings from their related Zoom Cloud accounts. The configuration is setup to not delete the original recordings from Zoom Cloud.  The following is our Zoom Cloud recording process in each classroom:

-A/V assistant starts the Zoom session for the room using the Zoom client at 8ish am or whenever the day begins.
-They hit the Zoom "Record" button when a lecture starts.  When that lecturer is done, they stop the recording. When a new lecture starts in that classroom, they hit the Zoom "Record" button again, then stop when they're done, etc.
-Mid-day, the A/V assistant ends the morning Zoom session which makes Zoom Cloud start processing the morning recordings that occurred in that session.
-This means we usually have two classroom Zoom sessions daily, and each session contains up to four recordings.  Each recording is downloaded individually to Canvas Studio.  On most days when it works correctly, we end up with up to eight recordings for that classroom per day in Canvas Studio.

PROBLEM

It was reported that this year, occasionally a cloud recording or two do not make it from Zoom Cloud to Canvas Studio. The workaround is for our course editors to login to the relative Zoom Cloud account and download the recording(s) that didn't transfer manually.

TROUBLESHOOTING

My internal testing has shown two consistencies so far when a recording is not downloaded to Studio:

1. It seems to only happen when there are 4 or more recordings within a session.
2. It appears to always be the first recording within the session that is skipped.
3. It is happening for us in multiple different Zoom accounts downloading to multiple different Canvas Studio accounts, so I don't believe it's an isolated issue.

Has anybody else encountered this?  I wondered if there was a max number of recordings that could download within each session.  Zoom Cloud holds the recordings successfully even if there are four or more within a session, so I don't know if the issue is with Zoom, with Studio, or with the connection between the two that makes it work.
