My org just moved our Atlassian environment inth the cloud, and now when I inlucde Confluence links in Tems messages, I am getting enormous Confluence Cloud adaptive cards that cannot be removed. (If I delete them they come back when I re-send the message).
Unlike Microsoft adaptive cards, there is no X to remove them. They are redundant and inflate the message size unnecessarily.
I tried removing CC app from Teams but that doesn't remedy the problem.
