Closing and reopening an app or a website is already a good start to troubleshoot when something is not working as expected, GPS4.

I'll provide additional steps on how you can resolve this.

Start by adding Intuit as a trusted site. This prevents your browser from potentially blocking site content.

Then, make sure to use a supported, up-to-date browser. Unsupported versions or non-standard browsers often fail to execute the complex scripting needed for the scheduler.

After that, log back in and check if the Schedule window is now loading up.

Feel free to ask follow-up questions if you need anything else.
