Nothing, your class is available as long as the teacher is still there and you can enter it via the main screen. As long as the classroom has a red dot with borders around it on your timetable, you can join it.

If you are late for a bigger part of the class and you're afraid of missing out on important information - recordings of each class are available for the entire duration of the subscription.

Class recordings are usually added to the platform up to 48 hours after the class end and they can be found in the "Recordings" section on the platform.
