Antigravity Quotas for Ultra

I wanted to explore Antigravity’s coding capabilities and started with a Pro subscription and started hitting the limits very fast when using Opus 4.6, I kept upgrading my plan and eventually ended with Ultra $200/month plan and still hitting the limits super fast may be 25% better than pro for similar amount of coding. I felt this is ridiculous, I reached out the customer service, they said they sent it to backend team for investigation and will get back in 24hrs and usually sooner in most cases, I waited for few days and no one reached back and when I reached out to customer service again, they say, they have no visibility in how usage is being calculated and there is no point in reaching out to their backend. Very very disappointed with the level of customer service and the model limits for the highest plan too. Wondering if anyone else had similar experience.
To add, I was building a cross platform mobile app using Flutter.
