More reliable human support handoffs

Getting human help should be straightforward. This release makes explicit requests for a human a firm handoff rule for Zappy and gives support quality checks a way to escalate conversations that need personal attention.

Human help when you need it

• Your request for a human takes priority. Zappy now always hands over when you explicitly ask for a human. Support quality checks can also escalate a conversation, carrying its summary, escalation reason, and priority through to the support team.

Interface polish

• More consistent German interface text. German spelling has been standardized in additional interface messages.
