First, check notification settings on your phone
Check if you enabled push notifications permissions for Delta on your phone. If it isn't enabled, please enable it.
If enabled and still not receiving, reinstall the app
There are odd cases where during the installation process, we didn't manage to get your push notification token. In this case, a simple reinstall will work. No worries, your data won't be gone after reinstalling. Exchange account connections will need to be re-added as keys are not stored for security reasons.
