The time it takes to be able to @mention someone in a circle after having added her is not acceptable
It can take several minutes, and several trials, to be able to @mention
in a circle after having added her. Often enough, it simply doesn't work at all.
We need a faster and more reliable way, the users currently think it is simply not working.
EDIT I'm adding this GIF so you realize the experience we're all having when we try to add someone to a circle. It just can't be this way. If it cannot be instantaneous, then we need to warn our users about it. If it can be, then please let's do it.
