Classic SharePoint Online People Search Result Pages Not Working on Multiple Tenants

Hello,

I have several clients that use classic SharePoint online people search result pages as employee directories. They use classic pages because they are easily editable and process in-line JavaScript and CSS for layout/look and feel changes. Anyway, it appears that all classic people search result pages are not working on multiple tenants. Even the default classic search result page, OOTB, with no customizations does not work - again, across multiple tenants.

Is anyone else experiencing this on their tenants?

Thanks,

Joe
