Hello @Todd Johnson, does your contacts still in your online portal? Can you check it by going to htpps://service.ringcentral.com. My Extension > Contacts. Thank you!
When you save your contact in RC desktop app or RC phone it will automatically save in the contact details of your extension. You can log into your online portal and check your contact in your extension.
The contact are actually saved into your extension accounts in cloud. So whenever you log into RC phone or desktop app, it will automatically sync with your account and will display all the contact exists in your extension contact.
