How to un-block someone?

I am throwing back and forth a few challenges with a friend, but now I accidentally clicked on “block”. How can I reverse that?

sadly, I have to do it, what is your and his/her username?

Me (Gabs), his name is Tesh.

But appearently it got unblocked automatically, when I started the game again he wasn’t blocked anymore.

Hey, can you unblock everything that I blocked? I blocked a whole bunch of stuff to check and now I don’t really get any news.

Name is 123stw.

All done :smiley:
