What is MDS Room App? Where can I get it?

How do I postpone and book classes on the MDS Room App?

How quick can I book a makeup class?

Why are there no available slots for booking shown in my App?

Why should I book other Educators for makeup classes?

Why can’t I view next month’s slots on my App booking calendar?

I can view some slots of my Educator when I select 30-min duration. But when I select 45-min duration, the slots disappear. Why is this so?
