WhatsApp reconnection fails ("Something went wrong") — orphaned Manychat credit line ("Access removed") | Ticket 539380

Hi team,

I'm hitting a known blocker and need help escalating my ticket. Our production WhatsApp channel is down, so this is time-sensitive.

After re-authorizing the Manychat integration in Meta to fix my Instagram connection, WhatsApp disconnected. Reconnection now fails at the final step of the wizard with "Something went wrong."

Root cause (confirmed): in Meta Business Manager → Billing Hub → Credit lines, Manychat's credit line allocation shows "Access removed" but is still attached to my WABA. Meta rejects sharing a new credit line while the stale one is attached. Meta support confirmed in writing that only Manychat (the BSP) can remove this allocation — I can't delete it from my side.

Already ruled out: Meta authorization is OK, no payment method on the WABA, currency USD, 2FA not involved (fails before the PIN step).

Action needed: remove the stale credit line allocation and re-share Manychat's credit line with the existing WABA (not a new one).

Ticket: 539380 (Pro plan).

​@cata_rendon  ​@Fabio Gaulke  — I saw you helped with an identical case before. Could you please check ticket 539380 and help escalate? I'll gladly send the WABA ID, phone ID and screenshots by PM. Thank you! 🙏
