Whatsapp Messages in random order

It is learned for users to divide individual information in Whatsapp into different messages. So I decided to use different steps to split in Voiceflow.
Unfortunately it does not work.
The steps of Whatsapp messages arrive in random order.

Hey! What region of the world are you based in? I wonder if this is a latency problem.

Can you give more details on when this happens? Is this on the Voiceflow testing tool, or when testing directly on whatsapp?
