If you use Facebook and Instagram for your business, you have to watch this video. Very often people don't know or understand who controls their pages, who controls the ad accounts, who has admin and who doesn't. The first thing that you have to know is that your meta business account is the hub and is the most important thing to keep safe and secure.
Now the meta business account is what controls your Facebook pages, your Instagram pages, your ad accounts and your pixels, as well as other assets such as your WhatsApp's accounts. Your meta business account should be owned by you, the business owner or people in your business. Very often we see that agencies or ex employees have set up this meta business account and if they don't give you control or they have left and you don't have access, you really are gonna be in trouble.
I would strongly suggest straight away go do an audit on your meta business account. Make sure that you own it and you have full access to it. Then take a look at other people have access to any of their assets.
So many issues can happen if you're not in control of this. It's vitally important that you go do it now.
