Hi Rocio,

Once you've made changes to the bot, type in /restart to replay the bot and see the changes made.

I'm sorry, could you please be more specific and detail about the group you are referring to?

Yes, it will add the numbers and not the string.

You can use the NLP fallback button node type. Let me know if this helps.

I'm afraid this is not available. The bot can be linked only to the FB page and not profile page.

We are experiencing some issues with Viber and currently looking into it. Will update you once the issue is fixed.

You can do this via variables. Create 3 variables and assign two of them with some values. Then, the third variable can be used by {c}={a} + {b}..

Hi,

You can use the Re-engagement feature to broadcast any message to user's at a specific date/time.

I'm sorry, this is FB limitation. However, if you do not want this, then the user choice text message length need to be less than 20 char.

Yes, this will work.
