I am having issues with my calendar not working, having to re-install it constantly to have the schedule load. We have two different android phones with the calendar installed on and both are experiencing this issue. The calendar works for a short period before it appears to freeze and we cannot view anything unless if we uninstall it, and re-install all over again.
