Hey Liam- I've noticed when trying to point the autosave/default save location to (for example) the 'N:\' drive, when testing with the exam account, it won't default to the right saved area.
On the actual ExamPadPlus software, it won't autofill and requires the user to browse; we want to limit where possible any user modifications and make it as simple as possible for the exams invigilators/students-
