App disconnects from metro server every time app its sent to the background

I’m in the managed workflow. Every time i send the app to the background it disconnects from metro. This is happening on both iOS and Android. This is the warning that i get in the console:

Cannot connect to the Metro server.

Try the following to fix the issue:
- Ensure that the Metro server is running and available on the same network
- Ensure that the Metro server URL is correctly set in AppDelegate

URL: 192.168.1.121:19000

Error: The operation couldn’t be completed. Socket is not connected

Any help solving this issue would be much appreciated.
