The budget for this ad set must be at least [your minimum budget]. Please edit your budget in your ad set to enable the delivery of your ads.
Why did this happen?
This error occurs when your budget is too low for your ad set. To drive consistent delivery for your ads, your ad set needs to meet a minimum budget. Minimum budgets are calculated as a daily amount, but apply whether an ad set is using a daily or lifetime budget. For example, if you're using a lifetime budget for an ad that's going to run for five days, the budget must be five times the daily minimum budget.
How do I fix it?
In Ads Manager, edit your ad set and adjust your budget so that it meets the minimum budget needed to run your ad.
How do I avoid running into this error in the future?
When you create an ad set and choose your budget, look for any warnings that notify you when your budget is too low. Adjust your budget to ensure that it meets the minimum budget guidelines.
