Facebook Page Admin Can now see EVERYTHING that do Advertiser Even admin isn't in Ads Account !!!!

Hi

Previously I run few ads campaign for my clients as an "Advertiser" on their pages and while I boost a post, they just see "Boosted" on the bottom of that post. That help us to keep some info confidential from the admin.

But recently when I set a campaign, my client direct call me and asked:
- Why the campaign cost is lower than full budget?
- Why you select those age limits [he saw the age limit]
- What is the reason for both gender

Then I asked a question to Facebook Help community and one of the team member ensure me that admin shouldn't see the spend budget.

Here is her ref. snapshot: Screenshot by Lightshot

After few days, my client hire another advertiser and boost another post album from his page. Then I see a strange thing. Now I can also see everything, even the Advertiser name, though I'm not the admin of that page, i'm just advertiser.

This is how the I saw while Advertiser set a campaign to boost the post:

And when I click "Boosted" Button, this is what I'm seeing:

Now see the red marked area. The spent amount, the advertiser's name and the campaign budget everything is now showing up !!!!

If such thing happen then what's the benefit to hide the primary results only using "Boosted" button. !!! They directly can use "View Results" as we advertiser can see before or now.

Do anyone have any idea about this? Any similar experiences?
