Submitting screens through this lesson

Do my students submit here in this lesson 12 or wait until all screens are done?

I am afraid they won’t be able to change anything later

Yes in the final bubble (13) each student submits one page for the app their group is developing. The pages will be combined together in Lesson 13 into a single app. This lesson took my students 2 days to complete. Before students submitted their page, I made sure all of the other group members gave feedback and necessary changes were made.


Can you (or anyone) explain to me how a student creates more than one screen in bubble 13 of Lesson 12? A few of my groups have more screens than they have group members. I just want to make sure I have them do it correctly before we combine in Lesson 13.
