Hi Clive FW,
Thank you for reaching Microsoft Community. I understand how this concern impacts your day-to-day productivity with the device.
May I know how are you accessing Zoom on the device? Are you using the Zoom desktop client or just accessing it through a web browser?
What Windows version, edition and OS build is your Surface Go 2 running on? To check, see Windows specifications section in Windows Settings > System > About.
Did this worked fine before, and issue only started to occur recently, or this had been going on ever since you first got the device?
Does this issue only occur when using Zoom or also when using other applications such as Teams?
Kindly try first running these steps below to make sure that the device has all the updates needed:
1: Run Surface Diagnostic Toolkit
See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com)
2: Check for Windows Update
Go to Windows Settings > Update & Security and select Check for updates
Make sure all updates need are installed including Optional updates
Let me know how it goes and we may also recommend other troubleshooting steps once we have received your responses to the questions above.
Kind regards,
Marrion
