Restore Disabled WhatsApp API Account

My WhatsApp Business API integration for quickfix.ltd has suddenly been blocked. The dashboard now shows “Account status: Disabled – This account doesn’t meet our policy guidelines.” Just before the lock-out I changed a few items: I updated our API key and adjusted some policy settings, so the problem is almost certainly tied to those edits. No other settings, webhooks, or rate-limit parameters were touched. I need someone who knows the Meta / Facebook Business Manager flow inside out to: • Pinpoint exactly which new policy or key change violated the guidelines • Guide me through (or handle) the appeal / re-verification steps • Re-establish full messaging functionality on the site with zero data loss • Test and confirm that webhooks, templates and number quality score all return to normal Access to the Business Manager, Cloud API console, server logs and current key set will be provided immediately after hire. If you have previous success reversing a disabled WhatsApp Business account and can deliver a quick, documented fix, I’m ready to start right away.
