I have created couple of site columns using PowerShell (CSOM) script in SP online site. I have added all these columns to libraries using PowerShell (CSOM). Later I have migrated hundreds of documents to different libraries which contains these site columns.
I want to implement search refiners. So I wanted to add few of the created site columns to RefinableString properties. When I am trying to add the crawled properties to the Refinablestrings, I am not able to identify crawled properties for created site columns.
I have created site columns two days before and migrated data 24hrs ago. I think this time is sufficient for crawling.
