Hi @zariah ,
Thank you for reaching out to us!
The issue probably occurs because the URL associated with the search engine used to open the PDFs has not been allowlisted. To view allowlisted PDFs, all necessary URLs must be included in the Allowlist filter under the Security > Web Content Filtering policy for iOS. For instance, if you’re accessing PDFs via Google Search, both the Google search engine’s URL (e.g.,https://www.google.com/) and the URLs of the PDFs themselves must be added to the allowlist.
Hope this answers your query.
Cheers!
