ASM Geolocation to block Exchange 2016 with APM

Hello,

I have the Exchange 2016 with LTM and APM (using iApps) all working fine with APM and LTM. Now I enable the ASM with main goal to use the Geolocation protection but is not blocking or doing anything. I do have the XFF enable and I can see in the sessions the correct source IP but the ASM is not blocking it, any idea?
