When does feature arena unlock?

Kbugii

I’ve been searching for a while now. My son just got into the game about 3 months ago. Does anyone know what the requirements for feature arenas to unlock? He’s over lvl 30. He’s got a decent sized roster. And he’s passed 90 days on the account.

They changed everything around with arenas. To access featured arena you need to be uncollected now
