@zhenyi Using Lucky I've started getting the error 'Unexpected response: - userInfo: { }' instead of search results. Any idea what is happening?

@dustan It means google.com is returning a non-200 HTTP status. If this issue persists, it's likely a 429 Too Many Requests error. (I'll make the error message clearer in the next update.)

Are you getting the same error on both WiFi and cellular?

@zhenyi The issue is only appearing on Mac for me so it is just Wifi. I have no problem on iOS even when on the same WiFi network.
@dustan Can you upgrade to version 1.1.5? It won't fix the problem, but at least we'll see a more detailed error message.
@zhenyi The error has been intermittent. I've upgraded to 1.1.5 and will pass along the detailed error message when it appears again.
