Can anyone explain how this f*** facebook account centar works?

I was able to run with one facebook prpfile few instamrag accounts and ads on them
Now every instagram accounts wants one facebook accounts since this sh*t of account centar appeared
How to fix this?

every instagram account needs a facebook page too in order to run ads, insta as you know its property of fb and all the ads are run from there

i changed facebook account name but my id is active now. What is something else ???
