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 :+1:

Hello @GregorWilson

This usually points to App A being in a bad state, not a prompt issue, since your other Vibe app works.

Quick things to try:

Duplicate App A and test prompts in the copy. If it works, the original is likely corrupted.
Remove any large or complex logic blocks and retry.
Recreate the app and copy in only the basics to find what breaks it.

There’s no manual “reset AI context” yet, so if duplication doesn’t help, rebuilding is often the fastest fix.
If it still fails, send the app ID to monday support so they can check backend flags or logs.

Gregor,

I have been dealing with a very similar issue, but with a bit different symptoms. I would like the opportunity to discuss in more detail.

There is no ability to make duplicates of apps - or am I missing something?

That does sound like the app itself got into a bad state rather than anything you’re doing wrong, especially since another Vibe app works fine in the same account. I’ve seen similar behavior where an app just stops responding without errors and recreating it was the only real fix. There isn’t currently a way to fully reset an app’s AI context, so cloning or rebuilding the affected app is probably the fastest workaround. I’d still recommend reporting it to monday support with the app ID so they can check the backend and hopefully prevent it happening again.

Hello @Bkostinsky The only workaround is to create a new app and manually recreate the setup from the old one, adding pieces back gradually to see where it breaks. If the app is stuck even with a very basic setup, it’s likely a backend issue and support will need the app ID to reset or investigate it.

Hi Brandon, yes that would be good! I also don’t think there is a way to duplicate an app either?

There isn’t a feature for duplicating the app or even the data source itself. If you want to recreate it you’d have to do so manually

Hi @GregorWilson I’m Amichay Even Chen from the vibe team

Sounds like a bug with the specific vibe app, better open a ticket with all the details so our devs can take a look and free it.
Another quick way to fix is trying to revert to the last succesful version, and prompting again from there (scroll up the chat and click “undo this” on the last successful edit)
