Whatsapp File Transfer

Hello Everyone,
I am facing a weird issue where WhatsApp File Transfer (images, voices,...) is being blocked when I enable web filter (the default with allowed unrated category) and application control (attached snapshot for reference).

The Firewall policy is very basic with deep-inspection enabled and the ceritificate is added to each users device in the root certificate authority.
Everything is working fine but we are unbale to send/receive images or videos on whatsapp windows application (the web and mobile version of whatsapp is working fine).
Thank you for your support.
