If these procedures don't fix the problem, reset the network settings and download available software updates from Apple.
Actions taken on my i Phone are not acting in that manner.
When your i Phone won't receive email over a Wi-Fi connection, perform some basic troubleshooting to remedy the problem.
Verify your Wi-Fi connection and email server settings, and then reset your email account.
When you setup a Google account (and enable Calendar by default), your Gmail calendars should sync without a problem.
These days, the setup is so easy that it all happens automatically once you sign in with your Gmail/Google credentials.
But there’s this remote possibility that Google/Gmail calendars are not synced to your i Phone’s calendar and that can be a big problem.
If you rely on mobility and your calendar a lot, this is going to be a very huge issue. It’s entirely possible that you switched off Calendars when setting up the Gmail account (intentionally or accidentally). Also, after turning it on, quit and re-open the Calendar app.
After the “demise” of a way for apps to use “push” in i OS 7, apps like Gmail have to rely on Manual refresh or something called “Fetch”. The Fetch/Push settings seem to work for Calendar events too.
So, if you’re not seeing your Gmail Cal events show up on your Calendar, this is one of the things you should check.
When you pick a time interval (after selecting the Fetch method), the Calendars will automatically fetch data from your Gmail calendar at the set interval.
For Manual, you will have to pull down to refresh the calendars (from within the Calendar app → Calendars.) If nothing works, remove the Google account from Mail, Contacts, Calendars and re-add the account. Just before you add, make sure there’s no restriction in Gmail Calendar.
