I*'ve received an email telling me I need to confirm my email address for Trello. In doing that the system that I've got an Atlassian account, and rather than allowing me into Trello says I need to log into Atlassian and link the Trello account. So I logged into Atlassian following the link provided. I can't find anything which tells me how to link these accounts, so I continue without them being linked. This raises risks. Can you please tell me how to link accounts so the data is protected and available to me? Thank you.
