Protect PDF Rest API - Not Working

As the title states, a call to operation/protectpdf endpoint is running without any issues, but the resulting pdf in AWS does not have any permissions set on it. At one point, this process was working. It was only until a few days ago that it stopped. I have attached some screenshots that show the following to confirm the process is running without issues.

1.) Fiddler capture showing initial call to .../operation/protectpdf. Shows request body and resulting 201 Created with pooling url

2.) Fiddler capture cont. showing final call to pooling url with status = done

3.) Resulting PDF generated from the process. You can see that there are no permissions set

4.) Last correctly generated PDF before this process stopped working. Clearly shows that permissions have been set on the file in the header

We are currently trialing Adobe PDF Services and have loved the product so far. Have not run into any other issues except this one. We appear to have sufficient quota, so I dont think thats an issue. We never receive a 429 HTTP code either. At this point, I am not sure what the issue could be. Are we incorrectly defining the information in the body of the request?
