Hi @hwesternes, we're working on it currently. There are two parts to the work: 1) making sure the charge models are available in all entities within a multi-entity tenant, and 2) making sure that Product Sharing works with the new charge models.
It is expected that the work will take a month or so to complete, but that's just an early estimate.
I'd love to hear from the Community here if Product Sharing is critical, as we'll likely release support for item 1 before item 2.
However, in the interim, we're able to turn the new charge models on in *one* of the entities within a multi-entity tenant, if, for example, you'd like to test in Sandbox. If this is interesting option for you, please reach out to Zuora Support and ask them for the new charge models in the one entity that you're interested in.
Hope this update helps. I'll provide additional updates as we make progress.
Thank you for your patience!
