Have lesson active all day
With remote learning, you should be able to have the lesson started and playing all day so that students can access whenever they need to. Or having a pre-scheduled time so that you can set it up in advance and not have to go start the lesson. Students now need to access on their own.

Just fyi you can have a live lesson and an asynchronous lesson. I do this all the time. I'm a virtual teacher. If students use my asynchronous link after the live lesson... their answers go into the same lesson for me to go back and review later.
Use the link that appears when you first start a lesson for the live version.
Use the "assign" feature on your lesson in the dashboard of lumio to create an asynchronous link for students.
