Hey Rosa!
Hmmm -- Do you mind explaining how each member is set up in your workspace?
If you have multiple team-members in your workspace added by using the 'Add Member' button in the 'Members' page, team-members currently don't have the capability to see other's Lindies
However, if multiple users are logging into the same workspace with the same credentials, there is no way to prevent other users from seeing eachother's Lindies or tasks at all
If you could give me a little more information of how your team is currently set up, would be happy to explain!
