Video and audio keeps glitching and freezing with therapist

[Lovebubbles44]

Hey, i have been having a lot of issues with zoom lately every time I meet with my therapist virtually. The video and audio will be great at first, but then around 40 minutes into the session it will start to freeze, and glitch out. I read that if you use zoom for free, that it will only give 40 minutes before it stops working. I asked my therapist about it, but she said she has a subscription for zoom. So I am wondering if I need to also pay for a subscription as well in order for it to stop glitching? I also have zoom meetings a lot with other people and hardly ever have any issues with glitching or freezing. So I am stumped and do not know what to do.
