title says it all

Yes.

when?

You have to be patient with it.
Someone else had this "problem" earlier, and someone in that said that it may take a while, it just has to update, which might take some time.

k thanks

You'll stay unranked until you've played at least 2 games. Once you've done that you just need to wait for the next server update.

Is it Unranked or Rank 0?

I got banned a couple months ago and when I came back I was Rank 0. Maybe it's because I'm a custom belt, I don't know.

It's unranked.

Rank 0 =/= Unranked

It's a glitch, nothing to worry about though since it's restored after 2 games & a server update.
