The VPN might be the real problem here.

Great city - I had a chance to visit it some years ago, and wished I had more time to explore it.

Back to this - I had a similar issue some years ago - our corporate VPN infrastructure just didn't provide enough bandwidth. I didn't have to use the VPN for work video conferencing, but it was annoying because I couldn't access corporate documents while on work video calls, since those were only available when I was on the VPN.
Very likely to be the VPN here too, and if that is the situation you'll need to work with your employer to solve it.

Hi StephenB, I logged in to Zoom outside of the corporate VPN and it didn't lag, it worked fine. Many thanks for your advice.
