SharePoint Online Search Not Returning Data in People Search

So I'm working in a client tenant (O365) and have created a custom attribute in their User Profile service called "HideFromPeopleSearch". It's a boolean attribute and basically I'm flagging service accounts, etc. that we do not want to show up in the People Search. I have mapped RefinableString100 to this newcustom attribute so it's People:HideFromPeopleSearch. I have a custom Item Template that I'm using to render the values. I added RefinableString100 to this template and no data is being returned.

I'm just doing a quick console.log(ctx.CurrentItem) to view the data being returned and RefinableString100 is null for users with that attribute set. It's been about 3 days since I've initially set the value. I have also used Mikael Svenson's SPO Trigger Reindex script to request a reindexing of the users.

So what else might I be missing? I was going to give it until Monday and then reluctantly submit a service request with Microsoft.
