iCal/Google sync issues since iOS 8.2 update

Since the update to iOS 8.2 a few days ago, iCal on my iPhone 5s is not syncing with my Google Calendar. I have already reset the 2 step verification on my Google calendar permissions, checked to make sure events are in the Google calendar and not in the iPhone calendar, and checked settings to make sure the Google calendar is selected. The only thing I have not tried (because I'm worried that changes I made prior to realizing thisi was an issue would be lost) is deleting my Google account from the iPhone and reconnecting. Is that really my only remaining option? I'm stumped.
