We just upgraded to the 2.7 version of the scheduler (using Moodle 2.7.1+ with the default theme) and are noticing an issue with the scheduler's teacher "My Appointments" view:
The issue occurs when a teacher is in the "My Appointments" view and when there are other teachers who own appoints (e.g. My Appointments shows fewer appointments then the "All Appointments" view). If a teacher tries to move to a new page in the "My Appointment" View (either by clicking the page number or by clicking the "Next" link), they are instead taken to the "All Appointments" view.
Essentially, the URL used by the page buttons:
is missing the "&subpage=myappointments" parameter that keeps it in "My Appointments" view.
This results in there being no simple way to view anything beyond the first page of appointments in the "My Appointments" view.
