One app no longer responding to prompts, another works normally

Hi all,

I’m currently building two separate apps using the monday.com Vibe App Builder, and I’ve run into an odd inconsistency that I can’t seem to resolve.

  • App A: was previously working fine, but now no longer responds to prompts at all.

    • The prompt is accepted, but there’s no meaningful output or code generation.

    • This happens regardless of how simple or complex the prompt is.

    • I’ve tried rephrasing, simplifying, and starting from scratch within the same app — same result.

  • App B (created separately): works exactly as expected.

    • It accepts prompts and returns full feedback, explanations, and generated code with no issues.

Because one app works and the other doesn’t, this doesn’t feel like a general Vibe outage or prompt-quality issue. It feels more like the first app is in a broken or stuck state (possibly a corrupted session, context limit issue, or backend flag).

Things I’ve already tried:

  • Simplifying prompts

  • Refreshing the browser / logging out and back in

  • Creating new prompts within the affected app

  • Comparing prompt structure against the working app

Has anyone else experienced:

  • A Vibe app “silently” stopping prompt processing?

  • Differences in behaviour between two apps under the same account/workspace?

Is there a way to reset an app’s AI context, or should the affected app be recreated entirely?

Happy to provide logs, screenshots, or app IDs if that helps.

Thanks 👍
