After setting up my account, booked a new session with a new student using this screen (below), by typing a phone number, parent's name and student's name
I was able to successfully book the new session. But when I go to the 3rd tab, the student is listed twice. See screenshot below:
When I signed out and signed back in, the 3rd tab did not show the student twice. It was ok then.
EDIT: Also, in this case, Ben was the dad and Vic the child (student). I was expecting to see B in the bigger profile circle and in the top line and not Vic and V repeated twice.
