When you set up a Google account (and enable Calendar by default), your Google calendars should sync without a problem. These days, the setup is so easy that it all happens automatically once you sign in with your Google/Google credentials.
But there’s this remote possibility that Google/Google calendars are not synced to your iPhone’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. Fortunately, you can fix it easily.
Google Calendar Not Syncing on iPhone: Tips to Fix the Issue
• Check for the Calendar Switch
• One of the first things you should check for is a switch for Calendar.
Step #1. Open Settings tap on Passwords & Accounts.
Step #2. Tap on Google → if there is multiple accounts, Tap on the Google account you added → Make sure the switch for Calendars is turned on.
It’s entirely possible that you switched off Calendars when setting up the Google account (intentionally or accidentally). Turning it on will sync the calendars. Also, after turning it on, quit and re-open the Calendar app.
When you pick a time interval (after selecting the Fetch method), the Calendars will automatically fetch data from your Google calendar at the set interval. For Manual, you will have to pull down to refresh the calendars (from within the Calendar app → Calendars.)
Sync Default Calendar:
Step #1. Go to Settings tap on Calendars.
Step #2. Tap on Sync → Select All Events.
Also, just to be sure, tap on Default Calendar. And then pick a Google calendar as default.
No Google calendars showing? Re-check the first part “Check for the Calendar Switch.”
Syncing Google calendar on iPhone is pretty simple but simple things can sometime malfunction. If you are having trouble syncing your Google calendar, look no further, just check this fix.
