I have 2 children at different schools who are both using FFI. Is it possible to view the uploads for both children without having to logout and then login again?

Yes. From your dashboard you will be able to view the activity from every pupil/student that you’re a Supporter of.

You can view each of your pupils by school, class, and teacher, i.e. if you would like to see all of your pupils/students from a particular school, choose Schools and then you will be able to view a list of schools at which you have pupils/students.
