duration of meeting as basic user but invited by a business user

A business licence user is sending me an invite for a meeting. I am just a basic user, but only participant. It is a meeting 1:1, but after 40 min the meeting ends. By the host is business user and I am just participating. Is it correct that the meeting ends after 40 min. Do I have to by the Pro version to have a meeting without disturbance after 40 min.? Grateful for a short note. Thanks, K
