App Preview Not Loading for 4+ Days

Hi,

I’m experiencing a persistent issue with the App Builder (Code Assistant) feature in Google AI Studio. The Preview panel for my app, a simple “Simple Calculator,” remains blank and fails to load.

This issue has been ongoing for the last 4 days.

Key Details:

* Project: Simple Calculator app (built using App Builder / Code Assistant).

* Issue: The “Preview” pane is completely black/blank and does not render the app (as shown in the attached image).

* Duration: The problem started approximately 4 days ago and is ongoing.

* Code Status: I have not made any changes to the code since the app last worked correctly.

* Location: I am accessing the service from India.

Troubleshooting Steps I’ve Already Taken (No change):

* Browser: I have tried using both Google Chrome and Mozilla Firefox.

* Browser Mode: I have tested the preview in an Incognito/Private window.

* Cache/Data: I have cleared my browser’s cache and cookies.

* Network: I have disabled my VPN/Proxy and have a stable, high-speed internet connection.

Given the duration and the fact that the code hasn’t changed, I suspect this may be related to a recent backend service update or a regional issue.

Has anyone else in India or other regions experienced this specific problem with the App Builder Preview feature recently? Any suggestions or official guidance would be greatly appreciated.

Thank you!

I have the same issue, and apparently it’s related to the network because I am able to see the apps if I am connected to 5G with my phone.

Hi @Narendra_Chouhan ,

Thank you for reaching out!
This seems to be a temporary issue.
Please try the following steps:

  • Refresh the AI Studio page or reopen it in a new browser window.
  • Clear browser cache and cookies, then sign in again.
