How to remove myself as a Facebook page owner?

Hi,

I hope someone can help me, or at least give me some advice what to do.

I have sold Facebook page almost two years ago here, this one: 140k Full Green AdBreak Fanpage with USA Fans

few days ago I have received violation from Facebook because of that page, although I no longer have anything to do with that page.

I am not admin, or I do not have any other role.

and when i asked Facebook support, why I received violation ?

They told me that I am still the owner of the page…

how can it be ?

then I asked them to remove me from the page, but they can’t do it, this is their answer:

I had a look at that case and can confirm that your requests regarding pages or user accounts outside of Audience Network are only supported to managed partners.

they also suggested I go to the settings page, and remove myself. but i can’t do that because i don’t have access to that page since i’m not an admin.

What can i do now ?

Thank you

Maybe you’re a hidden admin on the page. Check it out here - https://business.facebook.com/creatorstudio?tab=settings_accounts

I have check it, but there is no this facebook page…
there are just my other pages.
