Why do we need this?

When you contact our support team, we might ask you to send a screenshot of your JavaScript console. You can find the JavaScript console in your web browser as part of its developer tools.

The console contains information about errors or other issues, which allows us to identify the root problem and help you better. In addition to the console screenshot, we would also like to know:

What browser version are you using? If not the latest, could you update the browser and try again?
Does the issue occur in other browsers? For example, if it doesn't work in Chrome, does it in Safari?
Does the issue occur in incognito mode (or equivalent)?
