We have taken every step to integrate Trello and Slack (added it to the Trello workspace and the Slack workspace, added the Slack power up to the boards, added the boards to the channels, followed the process for private boards, made the board not private, etc.) and we're still unable to attach a conversation to a card because after we add the card and click on Attach Conversation, we keep getting this error message:
Sorry, looks like I ran into a problem attaching this Slack message to the card. Please make sure that you have permission to edit the card.
