I got an invitation to participate on a folder from a company that i´m working with. I´m on a basic plan (just joined). The folder has over 3gb and it doesn´t allow me to access it - basic plano offers 2gb free. The only way to access the folder is by upgrading my account? Or is there a specific setup that the comapny with a payed account can use to grant me access without having to upgrade my account?
