title: Is it possible to use the user_id from one chat bot with other chat app?
body: <p>As I understand the user_id is a page scoped (psid). The question is: If two chatbots that using two app id's, have the same user_id for same users.</p>
  
  <p>If one boot got a message, and after a month I give permissions to the second chatbot: Can I continue the conversation from the second chat bot? Will I be able to use the same user_id's that I collected in my 1st bot? </p>
  
  <p>(I'm not asking about the 24+1 policy) </p>
