RK-A2

If a user types something other than what we asked for (like typing yes, no, skip, answer choice), we currently just repeat the question the user needs to ask. Please change this to:
1. We will respond to your question over email. For now, we will continue with the current flow. run the loader for 1 second. <continue with the current flow i.e. repeat the previous question.>
2. store what the user asked in a new datastore kind 'user_questions' containing the following columns: board, grade, subject, chapter, exercise number, question number, step number, question, email address.
