Why your bot is sending duplicate messages?

So if your bot is sending duplicate message, it might be the following reasons:

For messenger channel, It’s possible you connect more than 1 app in your page advance settings. Please make sure you only connect UChat app to your page.

For WhatsApp cloud API, it’s possible that you used the same webhook URL in two different apps in your Facebook Developer account.

That’s the most common reason, please double check above points, if you still have questions, do send email to our support.
