I have my work google calendar showing on my iPhone on iS 5.01.
Say its Monday, and I have an event on my calendar for Wednesday. But that event gets moved to say Friday by the organiser of the event a few hours later.
Unless I go into the calendar app myself to refresh it, that event will stay as scheduled as Wednesday even though in reality it has changed. I will also get the false reminder on Wednesday still if I don't go into the calendar app before the event date because it still thinks its on Wednesday.
Is there a way for your calendar to update automatically in the background, say periodically? I don't wish to have to open the calendar app regularly to catch any changed events.
