Just this week when i receive invitations to an appointment i cant get them on my calendar. Normally i would just open email, view the invitation and click yes will attend and it goes to calendar app and automatically to calendar on phone and on internet. Worked fine last week. Now when I click on 'yes' will attend, it gives me two options to complete task, #1 calendar or #2 internet. Clicking either goes to a mobile web page that shows the appointment and even yes it was successfully saved. But it never does make it on phone or gmail calendar online. Clicking calendar used to work. Sprint and HTC has given up on me and told me to do a hard reset.
