What happens when the account spending limit is reached?

When the account spending limit is reached, ads will pause automatically. The account spending limit is a budget control feature designed to help advertisers manage their expenses on Facebook. Once the total amount spent across all campaigns in that account reaches the specified limit, Facebook will pause the ad delivery to prevent any further spending. This automatic pausing allows advertisers to avoid exceeding their intended budget, ensuring that they can plan and allocate their advertising resources more effectively.

Advertisers can always adjust their spending limit or reactivate ads after reviewing their budgets and strategies, but it's essential to understand that the purpose of this feature is to maintain control over spending. The other options describe scenarios that do not align with how Facebook handles account spending limits.
