While I am liking Siri AI I find that it sometimes will just end a conversation. I can be going back and forth on a topic, and suddenly the input field is gone, and at the bottom of the window it says "Siri ended the conversation". Why does it do this? Once it has, the conversation is just an archive, there is no way to continue the conversation. Starting a new conversation of course forgets everything that came earlier so is pretty useless. I can not understand why Apple would make it work this way. The end point seems random, sometimes it is very quickly after a conversation starts, sometimes it never happens even after days go by.
