Freezing for Me Only

Hi Everyone

In the last few weeks my zoom freezes if I have the other person on much more than thumbnail sized.  I can still hear them and they don't see any difference to me; I work fine.

I have the laptop plugged in through ethernet cable and have restarted routers etc.

I have checked that I have the latest version of zoom and the laptop is less than a year old.

I want to be able to hold a larger meeting with breakout rooms so I really need to be able to utilise the full screen.

Anyone have any ideas?

Thanks

Emma
