Hey there,
I read in a github post by @stephens (use response selector for chitchat/faq · Issue #344 · RasaHQ/rasa-demo · GitHub) that multiple responses are not supported, and the first response is always returned. But this post was in Nov 2019. Is there any workaround for this yet? It is a pretty big handicap for using Retrieval Actions instead of setting regular utters in the domain.
Cheers.
