Premium Auto-Subscription Cancellation?

Hello, I would like to cancel my diamond premium account auto-subscription.

However, when I went into the FAQs, it only mentioned the profiles tab, but didn't specify where in the profile tab.

Can anyone tell me where, exactly, the button is?

Thanks

If you are v3, the link in the following doesn't work: https://support.chess.com/customer/en/portal/articles/1444834-how-can-i-end-my-premium-membership-subscription-

I'm on mobile right this second, so the settings page for v3 doesn't work. I'll try and post the answer a little later for that,  if no one beats me to it.

Not seeing how to do it on v3 ... might be that it isn't implemented yet since I'm getting a message that upgrades are currently only on v2.

So... the V3 is the one with the toolbar on the side, and the V2 is on the top, right?

Well, by default v3 also has the menus on the top,  except in Live, but if yours is on the side you are in v3.
