It's doing the same thing for me also in Legend League. It's been going on for a few days now.
The chess leagues

Is this just me? Or is it a bug?
Not a bug, just not enough people in your league to start

No, I've heard from many people the same issue. Apparently it just hasn't started in weeks and there's some problem going on

There was a bug introduced last week that was fixed. So, if that's from last week's division, staff are aware and looking into it.
However, it's very possible you'll have to quit leagues, rejoin, and play a game to get into a new division.

That worked thank you.

A bunch of people's leagues won't start. Everyone I've seen this with is stuck at 30/50.
As mentioned above, you may need to leave and rejoin to get unstuck.

I couldn't see my league in the homepage or access it.
You must have opted out at some point.

Really? Because it's going fine with me.
It only impacted some divisions from last week
