Google AI Studio Build Mode: Permission Denied for Existing App

Hello Google AI Studio Team,

My existing app B CHALAN PRO — Simple Billing & Udhaar opens successfully in My Apps, and Preview works normally.

However, Build Mode fails every time I submit a prompt, including simple READ-ONLY requests.

Exact error: “Permission denied. Please check your account permissions and project settings.”

Gemini 3.8 Flash shows Canceled.

Applet ID: ce8863d4-4a99-4607-a7d3-5dc6ba893dc9

I have confirmed:

  • I am using the original Google Account.
  • Age verification is complete.
  • The app appears under My Apps → By you.
  • A new chat and short prompts also fail.
  • Preview continues to work.

Please investigate and restore Build Mode access.

IMPORTANT: Do not reset, delete, recreate, remix, or restore my project. Preserve all existing code, checkpoints, customer data, licenses, payments, and application functionality.

Thank you.

Hello @Nafees_Ahmad ,

Your app (ce8863d4-4a9...) is active and intact, so nothing needs to be reset, deleted, or remixed.

Our records show that Build Mode prompts ran and completed on your app after your post, until your latest prompt reached the daily free tier token limit in AI Studio Build mode ("Quota exceeded"), which resets at midnight Pacific Time. Because each prompt in Build mode sends your conversation history and project files, long chats reach daily token limits faster.

To continue building:

  • Select a paid Gemini API key in the Build chat settings (Usage section) to build right away without hitting daily free limits, or start a new chat inside your existing app after midnight Pacific Time (starting a new chat preserves all of your existing code and project files).
  • If "Permission denied. Please check your account permissions and project settings." appears again when submitting a prompt, open Google AI Studio in Google Chrome in an Incognito window with browser extensions and ad/privacy blockers disabled, sign in with only that Google Account, and type a short test prompt directly.

Please let us know if the issue persists.
