Get site drives returns used_size_in_bytes in quota as total size of site for each drive

[pbansal]

I am using ListDrives graph api call to get the size of the drives in sharepoint site: https://docs.microsoft.com/en-us/graph/api/drive-list?view=graph-rest-1.0&tabs=http#list-a-sites-dri...

However the used_size_in_bytes in quota for each drive is equal to the total size of the sharepoint site. Is this expected or a recent regression?

We're experiencing the same regression in our environment. We used to be able to use ListDrives to fetch the size of each site's "Preservation Hold Library"; however, now the values are the same for all drives of the same site. See below for a sample. You can see that "Documents" & "Preservation Hold Library" have the exact same properties for "Quota". (Actual sizes are altered to protect privacy). Could anyone assist? Thanks
