App not found

This link opens fine on web browser:

But when it was opened from an iPhone 13 via home screen icon, it shows Not Found.

Other apps were fine though.

Has anyone experienced this before?

Update: just a moment ago the app on the browser shows Not Found

Also getting “Not found”. Have you tried opening the app in the Editor? If it has not been used much, it may need to be republished from the Editor.

No, it was last accessed yesterday evening and in the editor it shows published.

Sorry my bad, someone had renamed the URL and i wasn’t informed of the change. How can i close this thread?
