Zoom meetings on wrong laptop

While at my friend's house to help her open a meeting, I signed out of Zoom on my Dell laptop, and signed in on her iPad so that she could access a video on my laptop and share it with a group. Since then, when I try to host a meeting, everyone is directed to her iPad and I see nothing. I have tried logging out and then back in, to no avail. Is my only option to close my account and open a new one? She says she logged out then logged back in.
