Cannot unlock new levels in UNO Journey. In order . Why did I rank lower than someone with more cards than me? How do I add people to my Friends List?. It's no longer a test as someone has already tested this with me and it I see " add friends " but it's for Facebook, & even if I disconnect from Fbk. I want to know how to add friends on UNO & friends by their username? 8 (Authority) Answers, 1 Friend, 42 Followers . Add a friend in uno and friends.
