The Semi-Annual Enterprise Channel license does not include the Copilot option. To access the features enabled by a Copilot license, you need to switch to either the Current Channel or the Monthly Enterprise Channel. To use Microsoft 365 Copilot, you will need to switch from the Semi-Annual Enterprise Channel to one of the required channels. Once switched, you can use Microsoft 365 Copilot to translate all slides into English simultaneously, maintaining the slide design and layout, and adjusting the font size to fit each text area.
