How do I unblock a FaceTime contact which I have inadvertently blocked?

Go to the entry in Contacts. Scroll down to the bottom of the entry. If it says "Block this Caller", you have not blocked them. If it says "Unblock this Caller", you have. Tap to unblock.

You can also go to Settings>FaceTime>Blocked to manage the list.

When I go to Settings>FaceTime>Blocked the number is there, but there doesn't seem to be any means to unblock it. Clicking on it does nothing. ????

No worries. We've all done that! As long as you got it sorted, that's what counts.

Best of luck.

Ha! Apparently after all that tsuris, I hadn't blocked the person. I seem to need help both coming and going, and even then I run into myself. Thanks!
