Maybe delete the cache for this site on both devices and try again? What OS is on the laptop?
Edit: I just tried it on my Android tablet and it's now at the top where Dave just moved it to, not to the side. My phone is Android and I hate reading websites on a tiny phone screen
... but even there it's now at the top only. There's no room for it to be on the side.
And I should add that my desktops and laptops all have Windows 10 as the OS.
