The authorization flow does not return to the MCP client

If the browser opens but the MCP client does not complete authentication:

1. Keep the browser running and retry the MCP action.
2. Paste the authorization URL into an existing browser window if no tab opens.
3. Return to the MCP client and refresh or reconnect the Nordic MCP server.

On macOS, this has occasionally affected Vivaldi and Opera when the browser was not already running.
