My wife has just gotten a new Android phone and we share the same calendar. After the phone was set up by Verizon, I noticed it had all of the calendar items she had before her iPhone died, but new items were not being added. I added my Google account, which I thought would solve the problem, but it's still not picking up items I put on my phone and I don't get items she puts on her phone. In an attempt to resolve the problem, I turned off the sync to her account. When that didn't work, I turned it back on -- and managed to duplicate all of the calendar items she had on there from her backup! Can anyone tell me how to clear the calendar and then repopulate it with the items from my Google account?
