So I've opened up my react-native app in Expo today (using the iOS simulator) and I am creating by what looks like a debugging overlay.
Screenshot here:
I don't need this and it's blocking some of the UI for testing.
How does one turn it off?
You have the Element Inspector open. To toggle it off do either:
⌘+Dif you are in the simulator- Shake your phone if you are on an actual device
This should open up the debugging menu. You can then click on Toggle Element Inspector to close it.
