When the bot is live there should not be an option for the user to access message history. This should just be in the backend for testing purposes. It's really annoying because if you're typing a long sentence on two lines and you notice you made a mistake on the first line, you use the arrow to go up and botpress deletes everything you just typed.

As an alternative, You would prefer it to scroll up a line or to the beginning?

It should scroll up or down one line of the conversation input box so that you can correct a spelling error or suchlike.

Makes sense thanks for opening this. It has happened to me previously as well.
