Thank you for Proton Calendar security and privacy. Using PCalendar in desktop, I added (and it saves) descriptions for the type of appointment. I like I can modify prior to sending the invitation. However, in the ipad app and the phone app, those descriptions don't save as default. For example, a descriptor for a type of appointment is the cost of the appointment. I work with patients of adult and child age. So the default description for adult could be "$85 cash or check. 60 minute session" and for a child session "$55 cash or check. 30 minute session." But these descriptions don't transfer when using the ipad or iphone for scheduling purposes.
Thank you.
