If you've created contacts in Quo via Relay.app, you may have noticed that the contacts were created successfully, but you're not able to see them in your contacts list. This is due to a limitation of the Quo API where contacts may be created via their API, but are not visible until there is an associated conversation.
After creating an API contact, it will only appear in the Quo app—whether in the conversation list, contact list, or search results—if there’s an associated conversation with a matching phone number.
