Hello - my Ipad and Iphone both only synch about 6 weeks of history from my google calendar. I can see years of history when I go on the web and look at my google calendar. I have read various helpful answers on this forum about adjusting the ipad settings so that events are synched 6 months back (or indeed synch all events) back but it does not seem to help.
For some reason birthdays are the only events that show up historically. I think this lack of history is a recent development - possibly post IOS6? Any brilliant ideas would be welcomed. Thanks. Tony
