They have implemented something else called "omnichannel routing", but it's limited in what account types are allowed to use it, and if you use Messaging, it dumps all offline messages onto a single agent when they sign in, by design. There's plans "on the roadmap" to allow accounts to adjust this behavior but basically, no, there's no actual round robin capability to this day.
this is unfortunately natively not possible.
An option could be a 3rd party App from our Marketplace.
Also, feel free to check out our new Omnichannel routing.
