Removed Hub Site still display as Hub Site

Hi Hirofumi

The reason this happens is because you might have deleted the site without removing the association first. If the site is deleted the association gets orphaned and so far Microsoft has no SDK to remove orphaned sites. Although they are working on it and I see updates almost every week it would be good to keep an eye for the update on this.

This is what  I do for super clean SPOSite deletions :

$Iterations = "","1"
foreach($Iteration in $Iterations) {
          Write-Host "Iteration : " $Iteration

          Remove-SPOHubSiteAssociation "https://<<tenant>>.sharepoint.com/sites/<<site>>$Iteration"

          Unregister-SPOHubSite -Identity "https://<<tenant>>.sharepoint.com/sites/<<site>>$Iteration" -Force
          Remove-SPOSite -Identity "https://<<tenant>>.sharepoint.com/sites/<<site>>$Iteration" -Confirm:$false
          Remove-SPODeletedSite -Identity "https://<<tenant>>.sharepoint.com/sites/<<site>>$Iteration" -Confirm:$false
}

Hope this helps.

Cheers
