I have a Google App Script deployed as a Web application.
It was working normally, until this evening I discovered it would not load in Firefox or Chrome.
In Firefox I am getting this message;
Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://n-...-0lu-script.googleusercontent.com’) does not match the recipient window’s origin (‘https://script.google.com’).
Removed part of URL
The app is deployed: (Executing as myself, and is Accessible for anyone, even anonymous).
I thought the issue might be with LastPass as mentioned here, but I have disabled LastPass in both browsers and the issue persists.
