Hi @jencodb,
We haven’t made any changes in this regard and we don’t perform any extra ACL modification when writing files and folders.
I did some quick testing on my Windows 10 machine by adding the “Everyone” group with read-only permissions to my Dropbox folder in odrive. All subsequent folder and file downloads retained those permissions.
Can you elaborate on your use case for this behavior a bit? I would love to hear how you are using your Dropbox storage and how customized ACLs are used for your workflow so I can share with our product team.
