-Until the GA rollout is complete, the feature is still available for organizations on paid performance plans in the Early Adopter program. If you opt out of the Early Adopter program while on the per-category on-demand budget strategy, you'll retain the per-category budgets you've set and the ability to update them. However, if you switch to the shared on-demand budget strategy, you won't be able to switch back unless you opt in to the Early Adopter program again.
