I used to rely on "Read Aloud" in the old Edge (Edge-HTML)
So having this feature coming back in Edge 84.0 is welcome change.
But I notice annoying behavior:
When you are in particular page and click "Read Aloud" icon, the reading starts all over from page one !
This is more annoying as every time you reach to a page I return back to page one whenever I click "Read Aloud"
I hope this fixed in the coming versions.
Version tested: 84.0.522.40 (Official build) (64-bit)
