Unfortunately, the Anki site states that:
"Please be aware that to make sure we are delivering a high quality experience, we are launching Vector + Amazon Alexa support exclusively in the US and Canada. We will be announcing UK and Australia availability next year to ensure it works well for everyone in these countries."
To work around the issue and to enable Amazon Alexa, you need to download a GPS spoof program. Any will do.
Voila, you should have the "SIGN IN WITH AMAZON" appear under the "Things to Try" - and it works.

Instead of using an IR sensor to detect whether the Vector is craddled or not, a different approach would have been to use a microswitch. The circuit below is a minimal design using a
2N3904 transistor that would allow a load to power an USB device.
