I have problems with a policy where I include an application control where I block access to facebook, youtube and others, one of the applications that I allow within the control is whatsapp but it has presented problems since yesterday, the attached files are not They send and the messages are sent several minutes later, the same as when receiving.
I have been doing tests and by allowing the known applications the whatsapp starts working correctly, someone could help me know what the problem is if everything was working well until yesterday that I present this inconvenient.
My device is a Fortigate 90D
The only categories that I have blocked in the control of applications are: Botnet, Game, P2P, Social.Media, Update, Video/Audio and Unknown applications (now in monitor mode for whatsapp work)
The other categories are in monitor mode
