Resolution
To resolve this issue we advise our users to try one of the following options:
- Merge both messages into one message when you expect to send two messages with a short time difference to the same destination.
- Make sure a minimum delay of 500 milliseconds is elapsed between one message and the next message to the same destination.
- Stop sending messages to one destination until you get the Submitted (or Error) status event from the last message sent to that destination.
Cause
WhatsApp has a known issue where if messages are sent too close together they may not deliver in the correct order.
