Fibaro Strip LED and Alexa

I’ve logged this issue with Amazon but not heard anything yet.
I have a Fibaro LED strip in my kitchen which works perfectly with ST. It also used to work perfectly with Alexa - until Amazon updated the app.
It stopped working in Alexa and so I removed it - with the intention of setting it up again. When I came to re-add it, Alexa no long recognises the device and won’t re-add.
Has anyone else had this issue?
