Meta Business Suite

I need help; I can no longer boost ads for the following reason:

"As you subscribed to use Meta Products without ads, you cannot boost content. You can manage your subscription at any time in ad preferences."

I need someone to help me resolve this completely, so that I can boost and place ads on both FaceBook and Instagram.

I know it's a simple issue but I cannot resolve it, unfortunately. Can you please demonstrate that you know what the problem is and how to resolve it?

Additionally, I'd like to know how to place ads on tiktok, without paying the Apple charge
