OneDrive API returns 401 for some users when downloading files

Question

I wrote a script to download pictures from OneDrive. This script works well for one user. However, the same script returns a 401 error when attempting to download files using the url specified by @microsoft.graph.downloadUrl. What is strange is that I don't receive an unauthorized error when enumerating the files, it is only when attempting to download the files using the information provided during enumeration.

In digging into the problem, I noticed that the urls returned for the user that works are different from the urls returned for the user that receives the unauthorized errors:

Working urls start with https://rpgpbw.by.files.1drv.com while urls that receive the unauthorized errors start with https://my.microsoftpersonalcontent.com.

Do you have any idea of what might be different between these 2 accounts?

Thanks in advance for the help!
