Have the same problem, you can click the ā€œOpen Agent Managerā€ button on the top-right corner, then goto to Inbox. thereā€™s a ā€œProceedā€ button here that works for me.

Hello @Bilguun @Dse @Ruben_van_de_Rande, welcome to AI Forum!

I have tested this behavior in my current Antigravity configuration and found that the ā€˜Proceedā€™ button is functioning correctly in both the Editor mode and the Agent Manager. To help us investigate why this might be failing on your end, could you please provide your specific environment details and the version of Antigravity you are currently running?

Hi @Abhijit_Pramanik
