Instagram posts to the main fb profile instead of the desired page. How to setup?

Question

Facebook

Good afternoon!
Registered a business account on Instagram, linked to a managed Facebook page. It turns out that the phone now has 2 Instagram accounts, between which you can switch. The Facebook page has confirmed that the Instagram business account is now linked to it. But, if I choose, when posting a photo on Instagram, to share it on Facebook, then the photo gets into my personal feed. If you don't share on Facebook right away, the Facebook page shows that a photo was posted on the linked Instagram account - share it in the page's feed. I share on Instagram - the photo is again in my personal feed. Help Instagram does not help.

Where in android "publish"?
In the linked accounts menu, I select Facebook,

it expands on my managed pages,

I select the one I need by checking the box ...

There are no confirm buttons. I just go out, try to post - again in my feed. I return - the checkmark itself is not there again. If you put it on the desired page and do not exit the menu, it will jump to the top itself.
I can't figure out how to deal with this nonsense. Help me please!

Answer 1

Tie everything to individual numbers

Answer 2

You need to switch from a business account to a personal account and should immediately post to the FB page. If you need a business account, then disconnect the associated FB account and reconnect the business. After that, auto-posting from Insta to FB will work
