GDR3 now uses CALDAV as the calendar protocol for gmail. If you are viewing a shared calendar you will no longer have it once you upgrade to GDR3. To restore it click on https://www.google.com/calendar/syncselect
It did resolve the issue on all of the phones that had previously had a sync account. Thank You The phones had all lost the google calendars in the app Calendarpro after GDR3.
However I have not been able to make this work on new phones.
I still can not see google events in several of the calendar apps I have tried.
I can see them in the default calendar app but it is not robust enough for what I need.
