- I did not receive an invitation to a Google Calendar event I was invited to.
- When an event I'm invited to is changed, I don't receive a notification.
To make sure you receive notifications for new, changed, or canceled invitations, you need to update your default notification settings. See Customize your notifications.
With Google Calendar you can customize how and when you receive notifications. You can customize your notifications for new, changed, and canceled invitations. You can also customize your settings for invitation replies.
For instructions, see Change your default notification settings.
