Once it has been launched, how long do you have to wait if you want to pause a campaign?

You can pause a Mercado Ads campaign at any time after it has launched. There is no mandatory waiting period. However, it is strongly recommended to let a campaign run for at least 15 days before pausing it. This duration allows the campaign sufficient time to gather meaningful data, optimize its performance, and achieve its objectives. Pausing too early might prevent the campaign from reaching its full potential or providing enough data for informed decisions. The other options are incorrect because campaigns can be paused, and there's no requirement to wait for a conversion before doing so.
