A solo developer building WhatsApp booking bots for barbershops (n8n + LLM via Kapso) details a workaround after a client's number failed Coexistence signup three times with error 3441038 — Meta says it's tied to an inaccessible partner portfolio. Plan: buy a fresh prepaid SIM verified never on WhatsApp, run WhatsApp Business genuinely for 7+ days without linking Facebook/Instagram/catalog, connect via Kapso in the owner's own portfolio, then warm up slowly (reply-only, no marketing templates); fallback is re-registering as a dedicated Cloud API number. He also notes Meta disabled his own fresh portfolio three times in four days in September.
