Edge cases with S3 presign downloads in Production

[sfisher]

Some downloads seem to be having issues, even after lots of testing on dev/stage . IDK if these items are being stored differently in Merritt and our buckets or if other things are happening. Need to investigate and reverted deploy for now.

Examples:
