On the IO page, users have the ability to modify IO details such as the name, timezone, start date, end date, IO budget and IO budget setting.

The "IO budget setting" is represented by a checkbox located beneath the IO budget field. Checking this box ensures that the IO budget will automatically match the total campaign budget. When this checkbox is selected, users are not required to manually specify the IO budget amount.

Please note, if you change the IO start date to an earlier date, associated campaign start dates must also reflect the earlier date to begin running by that time. If the campaign has a later start date than the IO start date, it will not start running until the campaign start date is reached.

If the IO start date is changed to a later date, it will begin serving at that date unless the campaign has an even later start date. In that case, they will start running when the campaign start date is reached.

If the IO end date is changed to an earlier date, campaigns will stop serving once IO end date is reached, even if campaign end dates have not been reached.

If the end date is changed to a later date, it will continue serving until the last day of the IO end date, unless associated campaigns have earlier end dates.

If you change the budget at the IO level, it is possible that associated campaigns will start or stop serving based on the budget change that was made. The IO budget level is the master budget that all campaigns will serve to.

Once you've made the necessary changes, click "Update Changes" to save your updates.
