Using IOS7 on iPhone 4S. Gmail and Gcal. Some calendars to which I subscribe show perfectly on laptop, but an appointment or two on my iPhone is missing. Never had a problem before IOS7. Only thing that has changed is the IOS. Is this an IOS7 known issue?
I do know that if your feed is private (eg https) or generated from a personal account, you need to enable non-secure links (http) and add your device to your gmail account. I am having the same problem, but my feeds are generated from the small business gmail apps and are public links.
