Read API v3.0 not returning angle for PDFs

I've been using v3.0 of the Read API since June 2020. Starting two weeks ago, I noticed that when sending PDFs with multiple pages, the angle returned by the API is always 0, regardless of the orientation of the pages. After converting one of the pages to PNG, and submitting it to the same service, it returns the correct orientation angle.

I've attached a redacted version of one of the documents in both PNG format

and in PDF format

Also, here's a snippet of the JSON response for the PDF

    This seems to be a know issue with v3.0. Please use v3.1 as workaround, in the meantime, the product team will work on a fix for v3.0. Thanks.
