crazy.38experiment: a $9.90 R2 invoice on the Free plan blocks adding domains.
Community user crazy.38experiment says a $9.90 R2 usage invoice appeared although the account is on the Free plan and did not use paid storage or exceed R2 free limits. The overdue balance blocks adding new domains. The author says the Free plan did not allow a ticket and asks for the invoice to be reviewed or cancelled. A former Cloudflare community member replies that every plan can open billing cases.
