The experience you are describing is what would happen if you are not properly returning the ‘NOT_LINKED_RETRY’ fault.
As described in the documentation, https://musicpartners.sonos.com/node/405 (search for polling). While your service waits for the user to manually log in through the browser, it should provide to the getDeviceAuthToken call the ‘NOT_LINKED_RETRY’ fault response for a few minutes. Details for this fault can be found here: https://musicpartners.sonos.com/node/292.
