Microsoft Power Automate | Acrobat OCR fails when reading a secured .pdf
I am attempting to create a workflow whereby all invoices have OCR run on them prior to saving them in a SharePoint document library. The OCR stage fails in Microsoft Power Automate if the .pdf document is (SECURED). Has anyone found a fix for reading the documents, or how could I identify the (SECURED) .pdf then the OCR stage in the (MPA) flow could be skipped? Normal .pdf documents are processed and saved as expected.
Any help would be appreciated; thanks in advance.
