I've been looking at the account filing for medium/large companies and have noticed that every PDF of these filings seems to be broken. The issue is always that the cross reference table of the PDF is in the wrong position and/or the cross reference table points to objects in the wrong position.
If for example you try to open a PDF with a standard Python package like PyPDF2 or similar, the PDF will not be able to open because of this error. Although I can fix the issue myself, this seems like an issue that could be fixed.
This is nothing to do with the API, but thought it's worth pointing out if anyone has had issues
