For anyone else who freaked out today, seeing that your AI credits havent applied yet. YOU ARE RIGHT TO FREAK OUT! It wont auto apply.
Install Antigravity IDE, dont sync settings from 2.0 (close the popup when it comes). Get into Antigravity IDE, the banner will be top right where your conversation history normally is. It’s big, with a blue button that says Redeem.
Hope this helps. Google support has been useless about this, telling me it auto-applies, it’s a UI bug, etc., etc. I tried IDE to see if maybe it refreshes and it does. So thanks for no help Google, you almost cost me $100 worth of credits.
