Sometimes you may find the Chrome extension isn't quite working correctly 

It can be for a number of reasons including your PC/Laptop not having enough resources to manage all the tasks you are asking on it

If you do encounter problems answering calls a quick fix can be to toggle the browser extension off and back on

You can do this by following the instructions below

In your Chrome browser click the 3 dots at the top right of your browser, this will then open the additional menus as shown

In the dropdown list click 'More tools'

Then 'Extensions'

Next click to 'Update' the extensions in case there has been a recent update

And also toggle the extension, off, then back on.

If the problem persists we can look at the computer side but we may look to deploy a less demanding browser like which still allows you to utilise the browser extensions.
