I don't know about Android but on iPhone the FAB is doing two things synchronously...
1 - Scroll to top of content
2 - Load new content
The iOS way to do 1 is to tap the screen at the top... above the notch... and this works in bsky as expected.
So why not extend that to double tap for more?

tapping the butterfly already does that
