If you have multiple Teams linked to your Gmail account and you didn't set Sortd up that way intentionally, we recommend that you delete the Team that is not actively in use to avoid confusion. A Team in Sortd is essentially a billing account, so you shouldn't need more than one.
Make sure that you don't have any boards that you need on that team. From the Sortd menu on the left, click on View More Boards.
You should now see a list of all of your boards, it will look something like this. The heading is the Team name and the boards are underneath that.
Once you are comfortable that you don't need any of the boards that have been set up on the team, click on the Team settings icon next to the team name, which shows you what plan you are on and has a Delete Team button at the bottom of the page.
