You don't need to! The pricing doesn't kick in 'till next year. We want to give people time to migrate away or to implement a billing system manually. (And if anyone wants more time to do that, we're happy to grant it.)
If I reach out to support, will they be able to chat w/ me about what's actually happening? I'm pretty confused atm, and don't want to drown this thread with questions about what's actually taking place.
