I was able to block WhatsApp using Application Control. But users are able to access WhatsApp for last two weeks.
Is it because of the End to End Encryption Implemented by WhatsApp.

dear friend ,
just check which or how many users are using whatsapp &
on which platform because, whatapp have chating,voice& video calls, all ports are different ,
you need to specify them or check if they are using vpn or hotspot software to bypass the firewall policy .
may be little analysis will solve your problems .
if they are using hotspot or proxy software just block them with application control.
