The announcement post of arenas states
"Can I get demoted to a lower Arena?
YES! If you have been defeated in battle you will also lose Trophies, this can also cause you to be demoted to your Arena.
Example: You were at the Flame Arena I, but lost some battles, you would be demoted to the Terra Arena II. So KEEP training your dragons so they are the best!"
I have been promoted to metal arena...now I want to drop down to lower arenas (for dragon training purposes mostly) as I do not have decent metal dragons yet and want to train other dragons. I lost a few matches and dropped below 4400 threshold...but I'm still in metal arena.
Is this working as intended?
