Meta Subscription Disallows Adding Ads

Once you have bought a subscription (which prevents Facebook from using information from your accounts and from using cookies in Meta products), you will gain the ability to browse Facebook without ads.

Consequently, we will not be able to publish ads. If you purchase such a subscription for your account, which is connected to an ad manager, it will also prevent the agency that handles your business from adding ads.

It is worth mentioning that the subscription option only exists in the European Union.
