We've fixed the following issues:

- An issue impacting some customers where the ad scheduler would say that a given selection of screens and date range was available when it was not.

- An issue impacting some customers where schedules were being created with the incorrect time, which failed to properly account for timezone offset.

- An issue impacting some customers where optional banner or alternative ads were not properly saving during campaign creation or editing.

- An issue that prevented users from being able to navigate to the campaign permissions page.

- An issue impacting the imitate user feature for admins. This issue did not impact most customers.
