I blocked someone from my Snapchat's friends list and then deleted them and they did the same thing as well to me. Now, we want to add each other back, but we cannot figure out how to do this. Please help!
First you need to unblock him. Go to My Friends list and scroll down to the Blocked list. Tap on its name and select Unblock. After this operation, click the + icon on the upper-right and search for his username. He needs to do the same procedure in order to add you to his Friends list.
