Hi @sect2k, great you were able to find out quickly, and sorry I didn’t include a proper edit in the original post explaining it.
It was the same for us. We were suddenly on negative balance because the auto-recharge didn’t trigger. There was no invoice, no payment attempt from OpenAI. Once we added balance manually, everything returned to normal. The auto-recharge has been triggering normally since then, but we’re now monitoring the balance more closely just in case it fails again.
