Pfsense 2.4.2 ssl fitering using spliceall problem

[techbee1979]

So I setup a http and https web fitering using squid and squidguard.
Unticked http proxy and ticked ssl/mitm filtering, chose my ca cert created and spliceall so that i dont need to install the ca cert on each client, setup wpad, firewall, etc…

All is working.  I can ping wpad, can download wpad file for testing purposes BUT I cannot open or visit https sites.  And as i checked, it seems that my ca cert is not used by the proxy.  Is spliceall still works or not ?
