It seems there is a bug with the Moodle Mobile app in which any time a user accesses ANY of their courses, it will show as a concurrent access in ALL courses they are enrolled in which are still open. That is, if Student X access MATH-121 and she was enrolled in BIOL-125 last fall but the Moodle shell is still available/open, the Participants screen of both courses will show that Student X had accessed the course at the same time.
Our instructors like to keep courses open so students can go back and review resources and posts from previous courses as they move through their academic program, but they would also like to know which of those items are being accessed and it's confusing when they see that a student accessed the course (from the Participants screen) but don't see any activity logged.
This problem is identified in the notes of
MOBILE-782, but there is no reference to fixing it nor any other issues I can find calling it out.
(*this is my first time filing an issue so I'm not sure if this appropriately tagged as a bug or if improvement would be more appropriate. Also we only have 3.3 & 3.5 environments so while I am fairly confident this also affects 3.4, I can't say for certain)
