Troubleshooting
When WhatsApp stops, here is why and what to do
Short guides for the problems that take a business number offline: a coexistence link that drops, a restriction notice from Meta, or an error during setup. Each one starts with the direct answer and a one-minute check.
Why these problems happen
Almost all of them come from running a business on the WhatsApp Business App, which is built for one person chatting with customers, rather than on the WhatsApp Business Platform, which is built for teams, automation and broadcasts. ZapUp runs on the platform as a Meta Business Partner and handles the number setup, verification and migration as part of onboarding.
