The wording in the mobile app UI is confusing:
"Last Check in at {Date/Time}" is not actually the last checkin time for the Student in that Course.
It is actually the last time check-in attendance was run for that course.
We should be showing 2 timestamps here (imo) with details/clarification:
  1. Last time checkin attendance was run for the course
  2. Last time YOU, the Student, checked in
