So, Clipchamp (or another website) is complaining that your version of Chrome or ChromeOS is out of date?
That's easily fixed, by you, in about 90secs, quicker than calling Lee! :)
Click on the 3dot menu in the top/right of the screen, then click Settings in the menu -
Then click Safety Check, followed by blue Check Now button -
Then wait while the update is installed.
Updates are usually pretty quick. You may have to shut the lid at the end of the install if it asks for a restart!
