I can try to provide you as much info as I can. But last night the auto-trade window would show sometimes but it never worked, tried restarting WoW, reloading, making sure everyone had updated but no dice.

Let me know if there is any sort of tests/logs I can provide.

Please attach your SV located at ../World of Warcraft/_classic_/WTF/Account/account_name/SavedVariables/RCLootCouncil_Classic.lua

I put in discord issues channel!
