Why did my campaign stop running?

A campaign stops for one of four reasons. Check them in this order:

1. Your wallet could not cover delivery. Ads are charged from your SBX wallet as they deliver, and when the balance can't cover more delivery, the campaign pauses automatically. Top up your wallet and set the campaign back to active.
2. The daily budget was reached. Once a day's budget is spent, delivery stops until the next day, then resumes on its own. A campaign that goes quiet every evening and comes back every morning is a daily budget working as intended.
3. The schedule ended. A campaign shows Completed when its end date passed or its whole budget was spent — it did its job. Raise the budget, extend the dates or create a new campaign.
4. You paused it. Ads stop the moment a campaign is paused. Check the campaign's status and the ad's hide/show toggle, and resume when you are ready.

Stopping never loses anything: the spend so far, the results and the settings are all kept, and you never pay for undelivered views or clicks.
