Cannot turn off Event Alerts for shared Google calendars in iOS8
I am using a Google Apps account for my calendars and through this have access to several shared calendars.
When I go into the Calendar app in iOS8, I then press the 'Calendars' button at the bottom of my screen, then I am shown all my iCloud calendars in one group then all the calendars from the one Google Apps account together in the next section.
The iCloud calendars (Home, Work, Family) all have a red ℹ next to them, which when I press it, I am able to scroll to the bottom of that screen and switch off 'Event Alerts' under 'Notifications'.
But there are no ℹ marks next to any of the Google Apps calendars.
This means that all of my shared calendars will give me notifications all the time, and I can’t switch them off.
Is there any way to turn off event alerts/ notifications for specific shared calendars?
Many thanks!
