How to use someone upload of condo?

how do you use someone upload of the condo after subscribing it to the workshop? i see an upload spot I’m assuming that’s the where you do it but it’s not loading

On the main menu, go to the Condo section, and where it lists “Your Condo”, “Visit Player Condos”, and “Workshop Condos”, click “Workshop Condos”. In there there should be a “Subscribed” tab which should show the condo you subscribed to.
