Thanks Vincent,
Yes it’s in a new location as of Blender 2.8
It is now in the 3d viewport header under View > Viewport Render Animation
(you are using a 2.7 default layout which uses footers)
If anyone in the future is struggling with the 2.8 changes, make sure you check out the Fundamentals of Animation in Blender 2.8x
This is all covered in there.
