No Unlink OneDrive button in OneDrive system tray settings?

[Tim Slater]

I am trying to change my File Explorer OneDrive account from my a disused one to a current one. I read that I should Unlink OneDrive through the button in the System Tray on the OneDrive icon but there is no such button. I only have 2 tabs - Settings and More Info - and all the forums I have read say that I should click this button but it doesn't exist in my notification icon settings.

How do I change my File Explorer OneDrive to my new OneDrive account please?
