We fixed a couple of issues with the automated chat assistant so it always responds, even when there are no menu buttons to show.
- When there were no menu options to display, tapping "Menu" or sending the "menu" keyword left customers with no reply. The assistant now responds with a friendly "How can we help?" prompt instead of staying silent.
- In some cases an empty set of quick-reply buttons could cause the whole reply to fail, so customers received nothing at all. Empty button messages are now skipped so the rest of the reply still comes through.
