My Enforce version is 18.104.22.16818. I tested agent version 22.214.171.12418 and 15.5.0107.1001. They cann’t block send by file type on OTT application (Zalo, it like be skype or whatapps).
With version 126.96.36.19918, I have problems with block send by file type on Chrome and OTT application (I tried to block image file types)
With version 15.5.0107.1001, I still only have block send by file type on OTT application.
Anyone can help me?
