Either eliminate the chat feature or allow agents to opt out of use of that feature. Most of us don't need another chat application to check
Remove chat because we all have preferred chat applications that we use for our business. Messages in this app will go mostly ignored, which is not good when communicating with clients.

Hello, thanks for writing in!
To ensure you don’t miss out on any chats from your clients, make sure your push notifications are enabled. This way, you will be notified anytime someone downloads your branded app, you receive a message, or somebody sets you as their preferred agent.
To send listings as well as your branded link directly from your mobile phone number, tap on the Share button, and select your messaging application (or your preferred communication application). This will let any information come directly from you, utilizing your preferred method of contact information rather than using the HomeSpotter in-app messaging.
I hope this helps!
Thanks again,
