Hi,
So I'm looking to link a Trello board to our Confluence site to use a tool for managing page update requests etc.
I added the Confluence for Cloud power up. When trying to add a page link, it requires me to authorize my site by entering the link to my site. When I go to my site's homepage, the URL is https://(mysite).atlassian.net/wiki/home. However, when trying to connect to Confluence, the power up generates a "This is not a valid Confluence Cloud URL". As a note, I am the Site Owner and Admin.

I should also note that whenever I click Authorize, a separate window flashes for a split second before showing me that message.
I've also tried variants of the URL, but none of them worked. I get the same error.
https://(mysite).atlassian.net/
https://(mysite).atlassian.net
Can anyone help me out?
Thanks!
