The new firewall function does not work with private, withheld or unknown numbers 
The previous MIUI version had the option to do the above via a individual block section, would love this feature to work on future MIUI versions.
I`ve tried adding -1 to the blacklist and adding it into a individual group also.
I have confirmed that private, withheld and unknown numbers are handled as -1 calls. The MIUI does pickup my saved contact -1 from the contacts list, so it looks like the link between contacts and what is in-putted in the firewall section are not linking correctly.
