Scheduling a Space in advance gives you a longer window to promote your upcoming conversation. To schedule a Space, long-press the compose button on your Home timeline, then select the Spaces icon. Give your Space a name, select up to three relevant topics, then tap the Clock icon to select a date and time for your Space.
You can schedule up to 10 Spaces at a time up to 30 days in advance, and you can still create impromptu Spaces in the meantime. To make a change to your upcoming Space, tap Edit to modify the name, date or time. Only the name of the scheduled Space can be modified once the Space is live.
