for some reason all events lve added seem to of disappeared from my phone, all were added from my phone originally however upon checking via my computer all events are still on the calendar they are just not present on my phones calendar any more and wont seem to sync even tho they exist online. l have added a couple of new events basically because l need to remember a couple of appointments today which synced fine to my phone (and are viewable online) but all old events put in previously just wont sync to my phone again. typical, the moment l post this l find the solution for the issue. 1.
