The system added new boards that I can't delete

​@Sasha Selivanova The Free Plan supports 3 editable boards for the entire team and not for each team member. You cannot delete these other boards because you are not the board owner.

Your options:

1. Purchase a subscription – As Miro states, you can purchase a subscription and create unlimited boards. Since you have at least one other team member (i.e., “Juliia”), you should:
   1. Create a new paid team by going to www.miro.com/priicing 
   2. Move your boards to the new team.
   3. Leave the old team.
2. Remove other team members from your Free Plan team – If you truly are an owner of the Free Plan team, you will be a Team Admin and could remove all other members, therefore taking ownership of the boards in the process, at which point you can now delete them. NOTE: If you do this, all other team members will lose access to all boards in this team.
