I\'ve got virtual box installed. And when I look at the host > LAN > ip address is exp://192.168.56.1:19000.
How can I change it without disable the network? because
Sharing my experience using EXPO with Cloud 9 and AWS Amplify. Similar with you, the QR code gives exp://localhost:19000
As the Security Group has been configured to provide public access, I regenerate the QR code to have it accessible from public IP address of exp://X.X.X.X:19000, this can be scanned from IOS devices to EXPO.
