Yes, exactly correct.
For people creating new Asana accounts now, some percentage get this new capability, some do not. For existing accounts, Asana is in the process of migrating them to the new capability. They’ve said they’re going slow with the migration so as not to overtax their infrastructure, and they haven’t given any commitment as to when it’ll all be done. So you’ll have to be patient, but you will be able to switch between them, too, at some point!
