Worked immediately on my computer. Didn't seem to be working on Kiwi Browser on my phone, but then I removed the auto-capped first letter and found it to this site blocker to be case sensitive - which is fair enough. So now that I've got reddit.com instead of Reddit.com, for instance, it's working like a champ on both devices. As someone said below, it sometimes shows whatever site I've blocked for just a split second, then removes it which is good enough for me.
