Password protected file won't print on Ipad

Hi there,

I am getting password protected pdfs from a company on an iPad with IOS 12.6

I have the password. I am able to open the pdf with the password.

When I try print - I get the message "Without the proper password, you do not have permission to print this document" - the supplied password does not work and cannot print. I tried sending the document to another ipad with IOS16 and get the same message.

However i can open and print the document on Mac and Windows computers with no issue. 

I can also open and print other password protected pdfs on the Ipad without any issues.

The company sending the file is a large corporation and claim to be be unaware of any password setting that causes this.

Please assist in finding a solution.

Many thanks.

Duncan
