The only thread I could find about this feature is old, and no longer accepting comments. Marriott's FAQ page and info does not fully explain how to initiate the chat feature.

Can anyone tell me, if, after I press "REQUEST SERVICES" on the app, and the only choice that comes up is, "Call Us," Does that mean mobile chat is not available for this hotel? I have used mobile chat before, and that is how I thought I got there, although it has been a while.

Thanks!
