What does the status "Cannot Lower Budget" mean in Facebook ads?

Facebook ads have different specifications from Google and Yahoo, with a minimum amount that can be set at the campaign level.

This amount is the number of ad sets set for each campaign × approximately 100 yen (※ this may vary slightly depending on the timing), which becomes the minimum budget that can be set per day.

Therefore, when adjusting with Shiroufune's automatic bidding function to match the monthly budget (or period budget), if it is necessary to adjust to an amount lower than the minimum amount that can be set per day on Facebook, it becomes physically impossible to set that value due to Facebook's specifications, and budget management on Shirofune becomes impossible.

If a status of "Cannot Lower Budget" appears, please follow the comments in the operation guide and take the following actions.

① Increase the budget set in Shirofune

② Manage the budget manually

③ Adjust the campaign (or ad set) that is currently delivering ads
