You'll see a toolbar with some options - you'll likely currently be on 'Content', which should be followed by 'Devices'. From here, select 'Your Devices' from the block to the left. In the UK: likewise, click or hover over the 'Account and Lists' option on the top-right of the Amazon home page. Click or hover over this, then find 'Your devices and content', which was in the bottom-left for us.
