Flic Twist won't link to Alexa

[fraaay]

Hi. I'm in the UK. I'm trying to get my Flic Twist working with Alexa. During the set up procedure, when I'm linking accounts, I get the error message "Unable to link accounts. Your Alexa app needs an update".

It doesn't. I've checked.

It appears to link the account anyway, but then Alexa fails to discover any new device.

In case it's relevant, the Flic Twist dies work- it can control my Sonos. It's doesn't connect to my (Samsung) phone however, just the hub.

Is there a solution to getting it working with Alexa? I've reinstalled and re-linked various times to no avail.
