Do you have a Studio subscription?
Only Enterprise subscriptions are available for the Big Sur C4D plugin, ATM.

Right, but to @drunknbass' point, to access the Big Sur C4D plugin in the near future Studio subscribers will have to wait for what could be weeks, according to Otoy's FB and Twitter accounts.
Sure, we'll eventually get it, but for now it's either buy a monthly Enterprise subscription and cancel it ...

I recently updated my Studio subscription as well and I don't see it either.
It's still just showing PR5(Catalina).

Really wish I hadn't upgraded to Big Sur so impulsively, man.
