Support does not answer, no reaction. Trade-ID 982951
What is the onion address of the arbitrator? You can see it when clicking the trade ID.
For how long has the arbitrator not responded?
They are usually trying to respond at least every 24h.
I am not sure whose address that is. I guess they changed the addresses recently.
