I was told to install Planner Pro instead of Planner Plus (which was what I already used) in order for my cell phone & iPad to sync. I have had at least 5 emails back & forth with the contact person but I still can't get my calendars linked using my email address as instructed. I guess I will have to go back to my Google calendar. I love the Planner Plus but need a calendar that syncs to both my cell and iPad.
