Hi Praveen I seem to have the same issue now. The bot seems to work the first time I visit but I am unable to /restart the bot. I am overlooking something here. I should be able to restart and re-enter the conversation anything after publishing right?

I found out that once a page is chosen for a bot the page can not be changed. I have created a new bot an assigned it to another page without issues. No I am seeing the same behaviour. Even after unpublishing there is no way to change the page. This could be by-design.
