I've successfully linked a trello team to Slack and am able to add tasks with /trello add task.
I have a second team (separate from the first) that I would also like to add. I have been able to add in the Slack power up and the second Slack Channel is receiving updates from the board however if I try to link this board to the Slack Channel I get a message saying
"Slack channels in this team can only be linked to boards in an associated Trello team. To link <board name> associate its team, or move it to an already linked team."
How do I associate a second team within the same Slack workspace?
