Unable to share content from my professional Instagram to my professional Facebook (plz help!)

I have both personal and professional Facebook and Instagram accounts, and have all accounts linked through the Meta Center. For whatever reason, both Instagram accounts show in the Meta Center, but only my personal Facebook shows for the Facebook side. I’m able to share reels and other content from either Instagram to Facebook, but it only posts to my personal page.

I’ve tried everything that I’ve seen online. I’ve disconnected and reconnected my accounts on Meta Center. At this point, I’m ready to just scrap my professional Facebook and start over to create a completely unlinked Facebook page. However, I can’t seem to even delete my pro fb page! When I’m on the pro Facebook, I can’t make any changes via Settings, unless I am on my personal Facebook, which they have it listed as my “main account”.

Hope I explained this correctly! Any help would be greatly appreciated!
