Question
Can I connect multiple subdomains to the Sunshine Conversations app?
Answer
No, only one Zendesk subdomain can be connected to the Sunshine Conversations app at a time. However, a single Sunshine Conversations account can contain multiple Sunshine Conversation apps.
Note: If your production instance is connected with a sandbox account, you can only have one Sunshine Conversation app between the two. The subdomains of your production and sandbox instances can't both be used.
