We use the bot inbox and I just found a number of auto closed conversations that, IMO, should not be closed.
My resolution bot was set to close if the bot already answered the question. If you look at the flow of the conversation above it seems as if Intercom is taking a null response from the customer as an assumption that the answers helped and then closing the conversation. This is dangerous and I would ask that the conversation only be closed if a customer clicks 'that helped' or some other confirmation screen Intercom would send.
