The RefreshControl on DraggableFlatList never worked because the
library wraps its FlatList in a GestureDetector with Gesture.Pan(),
which intercepts vertical swipes before RefreshControl can detect
them — particularly with activationDistance=0 in position sort mode.
Replace with a toolbar refresh button (RefreshCw icon) on inbox and
list detail screens. The button uses an Animated spin during refresh,
matching the web UX. Removes all dead RefreshControl code and the
useless refreshControl prop.
