TZ300 (Whatsapp blocked on IOS Smart Phones cannot send and receive message)


I would like to ask a question regarding Application Control Protocol on Sonicwall TZ300. I recently upgrade the firmware to the 6.5.4 version, and after the upgrade, I received a lot of complaints from iPhone or IOS users that their Whatsapp cannot send or receive a message when they are connected to our network. I double-checked the firewall device to make sure that Whatsapp is not blocked and it appears that Block is on Disable Mode.

Please let me know if some of you had encountered this type of issue and what are the solution you that you can share with me in order for me to overcome this brain-itchy problem.

Thank you,
