Fixes for common issues

The following list contains frequent issues and their fixes and will be updated during development.

No connection to the Expo Go app

Sometimes the connection to the Expo Go app via the LAN can fail due to security limitations. To avoid the issue, open the developer tools after the Metro Bundler has started by pressing

d

Then select "Tunnel" above the QR-code. This creates a tunnel connection that bypasses the security settings and enables a stable but slower connection.
