Google AI Ultra 20x Family members appear to share Antigravity quotas. Is this intended?

I purchased the Google AI Ultra 20X Family plan for approximately 7,500 THB (~$230 USD), which is Google’s highest-tier AI subscription, not a standard or entry-level plan.

Given the premium price of this subscription, I expected each family member to receive their own independent Antigravity usage quota. However, based on our testing, the quota appears to be shared across all members in the Family Group.

Could Google clarify whether this behavior is intended or if it is a bug?
