I am an admin of a university Workplace. I enabled Trello integration.
At Trello, I enabled Workplace power-up. But when I clicked Workplace button, Trello said:
Your organisation has not enabled Trello or you are not logged in to Workplace. Contact your admin to activate it or make sure that you log in.
If you are an admin for a Workplace community, you can enable it.
I already logged in to Workplace.
