I used to use the calendar application on my iPhone. It might have been the Google calendar app. I recently I stopped using it because after trying to synch the Google calendar on my iPhone and my iPad, it ended up with a mess; i.e. I was able to add new events on my laptop but not on my phone. So I switched to Sunrise. However, now I notice that OF 2 on my iPhone does not list my schedule for the day correctly.
Any suggestions on how to deal with this?
