App Error: “Unable to fetch app definition. Error: App Blocked”

Hi everyone,

I’m experiencing an issue where my app suddenly shows this error message on launch:

“Unable to fetch app definition. Error: App Blocked. Please contact the app creator.”

When I open the editor, I also see two warnings under Info → Problems:

  1. “Since your app does not have an allow list, you need to explicitly acknowledge that your app does not need secure access control.”

  2. **“Changes to user settings will require immediate sync, which will not work when the app is launched completely offline.”

    l tried to troubleshoot the errors, despite the resolving the warning (especially 1)**…

    The error still remains the same….

    l tried to reach out to Appsheet Support, l find it strange to reach out to them through chat section.

    Please kindly help me resolve the issue.

You need to go through Support whether you like using chat or not.
