No more 40+ mins meeting

My zoom until few days ago could host a meeting for more than 1 hr+ uninterrupted. However, since i gave the my sign in details to a more than 7 friends to host some meeting on their devices on my behalf, no meetings is lasting more than 40 mins. This is a licensed account and i am not sure why i am only limited to, of late, to use freemium features. Why is this happening?
