The last six months were pretty intense. Two projects with tight timelines and some interesting challenges along the way.
So I barely had time to be active here.

Who from the React Native community is still around?

It’s amazing how easy it is these days to build a custom flow for over-the-air updates.
Just take the useUpdates hook from Expo Updates and wrap a nice little UI around it.
