When I click on the calendar app to adjust me period start date and log period details the app freezes up and wont let me do ANYTHING. I have to close out of the app and re open to be able to do anything else. but no matter how many times I try opening the calendar part it does not work and wont let me track any details because it goes blank. There always seems to be a problem with the calendar portion of the app... When will this be fixed once and for all?
