"Updating..." message on android device using snack

Hi all!
I’m totally new to react-native, so I hope this is a very simple question :slight_smile:
I’m trying to build some app using snack. So I have some views, some inputs on the screen and when I add some styles, like a flexDirection: “row”, snack doesn’t show any error, but on my android device (both, fisical and emulated by snack) it loads my app, but a second later it shows an “Updating…” message on top of the screen that never disappers. IOS works fine.
What does it mean, does anyone have any suggestion of what I’m doing wrong?
Thak you!
