Unhappy with all the changes

I really don’t like these features you have added, what was simple has now become complicated.  I have zoom appt yes that require emails and all contact information, but I also have other types of appts that don’t and its a pain for me to type in all the info just to schedule a block of time, and if I don’t know there email and I would like to post a reminder for myself it says my email is already being used…...it is not user friendly anymore and I want a refund and to cancer the service I will go elsewhere
