Append the native app version to the set of data sent as part of a check-in attempt. Attendance check-in is by far the area of the app that generates the most calls to us, and that we subsequently need to raise with ExLibris. We are always asked by E.L. what version of the native app the student is using. We can only get this by asking the student. If it was included in the check-in attempt we would immediately know.
