If you have access to multiple Bluelink accounts, you will need to switch between them
First, to check which account you are in, look in the upper right corner of the screen just to the left of the account menu (your picture).
Clicking on the face icon will open a menu. If you have access to more then one account, there will be a Switch Organizations menu item.
Select Switch Organizations to view the list of organizations you have access to. Then simply select the one you want to switch to and click "Switch".
Don't see the organization? Make sure someone has invited you to that organization. Until you accept the invite via the email invitation, you won't have access.
