Troubleshooting

An app won't start

• Check your network connection — apps stream from the catalogue.
• Try relaunching Brewser; each launch gets a fresh runtime context.

Graphics look wrong

• If an app renders incorrectly but works in Chrome, it may hit a WebGL conformance gap — please report it with the app name.

Sign-in problems

• Device-code sign-in codes expire quickly; request a fresh code if entry fails.

My hardware device isn't detected

• Confirm the app's manifest declares the capability (the picker only shows for declared APIs).
• For USB serial devices: check the cable supports data (not charge-only).
