Default [Q] NoRoot Firewall & Android 4.4 Problems

I've just updated to 4.4. (stock and Sense 5.5) on my HTC One.
I can't get "NoRoot Firewall" to allow any connections when it's "on", when it's "off" connections are possible.
I've uninstalled/reinstalled and rebooted etc several times.

Does anyone else use this firewall with 4.4. and can get it to work ?
I used it successfully with 4.2.1 and 4.3 and it's supposed to work with 4.4

If not, could anyone recommend any alternatives (rooted or non rooted) ?
But, I'd like something that can be set to a "prompt" state (like NoRoot).

Thanks for any help.
