I’ll just add another response to similar thread, as this happened to me(pro plan user) as well. I only started to use antigravity yesterday… woke up today to exhausted quotas… Curently waiting for chat with support as I consider this a BUG not a deliberate quota (I hope)
I have 2nd pro account That I have not yet used, this account limits also changed from 5 h to 7 days… not a single prompt was run just logged on(details below)
