PDF files in SEB for iOS (3.4.1) show as white page in SEB Proctoring Server

[ghost]

Describe the bug When using SEB for iOS (3.4.1) with SEB Server and enabling proctoring features, we see student's SEB screen captures in SEB Server. Unfortunately when opening a PDF file with SEB for iOS PDF viewer, in proctoring server we see a white page. We can see the title of the document, but the body is completely empty.

FYI : When using a server-side PDF viewer, the file shows perfectly in the proctoring server

1. Prepare a exam on SEB Server with a PDF file
2. Start this exam with SEB 3.4.1 on an iPad
3. Open the PDF file during the exam

Expected behavior Screen captures capturing student reading PDF file.
