I have the following issue: my Custom Site Columns are not appearing as Crawled or Managed Properties in SharePoint Online Modern Experience i.e. Communication and Team Site.
Created Communication or Team Site in SharePoint Online Created one site column. Created custom list and added custom site column. Activated all search related feature at Site & Web Level. Applied Re-Index entire site as well as custom list and wait for couple of hours.
As I navigate to Search Schema -> Search for custom site column under Managed & Crawled Property. It doesn’t appear, even I tried with prefix ows_ also.
Any thoughts please ??
