Google 行事曆在 iPhone 上有時出現有時消失的問題

似乎是九月開始出現的問題，到十月底為止還是有人碰到。

Workaround:

Navigate to https://www.google.com/calendar/iphoneselect and reselect the calendars you’d like to view. (Google Apps users can go to https://www.google.com/calendar/hosted/your_domain/iphoneselect, replacing ‘your_domain’ with your actual domain name.)
