We are experiencing the same issue we had last week with invoices being left in a pending state. It started on 18 October at 20:11UTC. It is now 19 Oct 03:30UTC. So sorry for not picking up this issue earlier. I have reported it to the dev team, and will remain offline until the issue is fixed. No need to raise a post as all trades will be amended and accounts balanced. Your patience as always is appreciated.
