where has the view page option gone

I apologise if this is a silly question, but I only use WordPress occassionally to update pages on my website.

Previosly to upgrading wordpress to the latest version, there used to be a “view page” option at the top of the edit page screen. That allowed me to view the actual published page rather that the preview page.

I am obviously missing something – but I can no longer find the view published page option on the edit page screen

Thanks for any help
