We are experiencing a new issue in Zoho Desk with PDF attachments. Until a few days ago, clicking a PDF attachment within a ticket opened the PDF for preview. Now clicking the same type of attachment automatically downloads the PDF to the computer instead of opening it.

This started at approximately the same time for multiple agents working remotely from different locations and internet connections. PNG/image attachments still open normally; the issue appears to affect PDFs specifically.

Please confirm whether this is related to a recent Zoho Desk update or known issue and advise how we can restore the previous PDF preview behavior.
