I\'ve created an expo app with exp init MyApp command and started it by running exp start in MyApp directory.
Then I\'m scanni
It was needed to reset "Draw over other apps" permission for Expo mobile app.
How that is fixed on Android 6.
Settings->Apps, press "gear", find "Draw over other apps" item and select it. Find "Expo" app, select it. Enable "Permit drawing over other apps" option in case it is disabled. Otherwise, disable and enable it again.
