Google calendars not showing in Calendar app on iPad Air?

It sounds like you have done all you can in settings, have you managed the calendars within the Calendar App?

I had a similar problem as you and went through the different suggestions with no success. What did it for me in the end was a simple "reset all settings" under Settings app -> General -> Reset. You will have to reconfigure a few things e.g. wifi password, wallpaper setting, ringtone etc; but you will regain access to your calendar sync.

(I updated from iPad 2 with iOS 6.1 to iPad Air, used the back up and restore option. The old gmail calendar (which used the exchange protocol) appeared but I soon realised that all the new events I added since then were not synced to the iPad air, i.e. the iPad Air is only displaying all the calendar items that were already there in the iPad 2 but it's not actually synced to the Google server. I then deleted the exchange account altogether (as I realised Google stopped supporting the exchange protocol in new devices), and tried to set up a new CalDAV account via the instructions by Google, and this is how I ran into "no calendar showing" situation)

Hi, did you manage to solve this problem? I have the exact same issue with my iPad Air and Google Agenda: can't get the latter to show up in the Agenda app. Only the iCloud one shows up.

I had the same issue 2 days ago, i got it resolved by connecting my iPad to my iphone, I turned on the Hot Spot in my iphone while the iphone itself is connecting to a 4G network, it works instantly though I couldn't figure out why.

Thanks for that - instant fix as soon as the hotspot connected the calendars all appeared!

indeed turning on the hotspot on your "Google" mobile device and get your iPad connected to the hotspot does help all calendars to show up. Many thanks!! I've been figuring out the whole day and finally this definitely helps!

cheers man!

thanks, your solution still works, 3 years and counting
