[2023] Guild Rankings Not Working

Are you currently in a guild?
Cannot reproduce the issue, anyone else?  

Maybe unlikely, but have you tried clearing your cache and trying again?  

I found the issue: You don't have Guild Battlegrounds unlocked. Once you unlock it, you will get access to the Championship Ranking.  

PJS299 said: I was wondering about that. What will they do when they get rid of GvG rankings but you don't have GBG unlocked?

Guild Rankings will probably be unavailable in general until you unlock gbg. But this is just my guess.
