Calendar very buggy

Often it will slip into a state where it will not actually render my calendar appointments. Other times the appointments show, but it doesnt render the times on the daily calendar (so I dont know when the events are).

Also, it sometimes wont let me open the details of an appointment. I can tap away at the appointment, but it just will not open.

Buggy program like something written by a senior in computer science, not a company supposedly dedicated to quality like Microsoft.
