Why are my WhatsApp order messages not being delivered?

WhatsApp only delivers business messages that use a Meta-approved template. Open Plugins, then WhatsApp Notification, and check: 1. Enable WhatsApp notifications is on and the API Token and Phone Number ID are saved. 2. Each event under Order Notifications has a Template name that exactly matches an approved template in Meta, with the right Template Language. 3. The Variables match the number of placeholders in that template. Use Send a test message to to check the connection, and set Default Country Code so numbers without a code still work.
