So I am having pretty much the same issue, but the funky thing is... I have two google calendars attached to my razr... my work and my personal... The personal calendar syncs just fine (adding an event on my PC shows up on my phone almost instantaneously). For the work calendar, I have to manual sync for things to transfer over... this used to work maybe 2 weeks ago and just suddenly stopped for no reason. I have checked all of the settings that people mentioned above (auto-sync is turned on, I don't use the power widget but I checked it, I disabled smart actions, I deleted and added the corporate google account and rebooted the phone in between...). Corporate Mail syncs fine, corp contacts sync fine... but the damn calendar no longer syncs without a manual push... Any other ideas? I also tried clearing the data in app settings for the application and service... that didn't work either.
