COMMUNITY

I have two questions:

1. If a user answers with more than one line of text (multiple messages), the bot repeats the question or uses the fallback condition. This causes some questions of the bot to be skipped if the person answers with multiple messages, rather than just one answer. How can I either limit the answers to one possible text message or not let the bot skip the next question or repeat itself?
2. I need the bot to wait 5 min and then "come back" to the user. In that time the user should think that the bot is working on his request and the chat should freeze. Therefore, it should not say "bot is typing" at that time and a user input should be ignored by the bot. Another possibility is that text input is disabled at that time. How can I do that?

Thank you in advance.
