I moved my files on 4.7.20 to Backblaze in preparation for the upcoming "just one storage location" rule.

Seems to work fine for CSS/images and so on but NOT for the Downloads app. All file download requests end up with:

{
  "code": "unauthorized",
  "message": "b2ContentDisposition is prohibited for unauthenticated requests",
  "status": 401
}

The browser URL looks like this:

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
