Problem:
The first message from Typebot sends successfully on WhatsApp, but subsequent steps (Step 2 or later) are not triggered after user interaction (e.g., button clicks or replies). This issue occurs specifically while testing with the WhatsApp preview.

Environment:
Platform: Self-hosted Typebot
WhatsApp API: Integrated and .env configured (WHATSAPP_PREVIEW_TEMPLATE_NAME, etc.)
Flow: Buttons/actions linked to next steps in Typebot dashboard.

Steps Tried:
Verified .env file (correct template name and URLs).
Checked Typebot flow (buttons/actions linked to next steps).
Logs don’t show errors, and the first message works fine.

Question:
Why does the workflow stop after the first message during WhatsApp preview testing, and how can I fix/debug this?
