Why is Facebook always a mess

Either I need to bulldoze all my FB account and start over, or FB needs to bulldoze theirs. The backend is a mess and I don’t understand it. I’ve set my connection and I can never figure out where my products are within FB. I’ve had zero orders through FB, but yet people have no problem ordering through my own site, Etsy, or TikTok. Something is wrong and this plugin keeps losing connection or something. I have no idea. I don’t want to mess with trying to reach a real person, because I feel like I’ve been in FB for so long, all their services from 15 years ago have been ducttaped together with modern ones. I have so many business and ad account that for one service, I have no idea what’s current. This plugin doesn’t help with any of that, and now, the only thing that shows up is “troubleshooting” even though there’s supposed to be a connection. No details show under the plugin for my account.
