Cannot turn off Event Alerts for shared Google calendars in iOS8

I have iPhone 6 with iOS 8.1.3, and this is the solution that's working for me so far. However, I had to use the Calendar app on my Mac OS X (Yosemite) - not sure if there is another option for PC. Basically, I added the shared Google calendar to iCloud and told Google not to sync the shared calendar to my iPhone, so the shared calendar now shows up under the iCloud list of calendars and not the Google list (and thus the option to turn off alerts). Note: the shared calendars I'm using are read-only, so I don't know how well this would work if you need to edit events from iPhone. I hope this helps, and if anyone has a better solution, please share!

1. Turn on iCloud calendars on iPhone and Mac.

2. In browser, open the shared Google calendar settings and copy the iCal calendar address URL.

3. In Mac OS X Calendar app, subscribe to the shared Google calendar. File > New Calendar Subscription > paste shared Google calendar URL > click Subscribe

4. Set Location to iCloud. I checked Ignore Alerts because I also didn't want them on my Mac.

5. The shared calendar should now be listed on your iPhone calendars in the iCloud section with the red i.

6. Press the red i and scroll to the bottom and switch off Event Alerts.

7. Remove the shared calendar from the Google list by going to https://www.google.com/calendar/syncselect and unchecking the shared calendars.

Thanks for these steps! Are the shared calendars you did this with private calendars? I tried to do this with my husband's Google calendar but it's saying there is an error subscribing, calendar not found.

I did it with public calendars. However, I noticed on my own private calendars that there is a private address ICAL option. If you can't see that option from your settings, maybe ask your husband to send you the link.

Hope this helps! Let us know if it works.
