Hi Vanessa,
The steps in the article you find should be performed by the global administrator. I suggest you contact your global administrator to follow the steps below and then wait some time to check the outcome.
- Navigate to the SharePoint admin center.
- Click settings.
- Select Classic experience in SharePoint Lists and Libraries experience and click OK.
- Back to settings.
- Re-enable New experience in SharePoint Lists and Libraries experience and click Ok.
Thanks,
Cliff
