Alexa Device Control - Voice works, Alexa App & Routines NOT working

Hi all,

I have had Home Assistant working fine for a couple of years but my Alexa control (Emulated Hue) has broken recently. I can control devices correctly via voice (“Alexa turn on bedroom curtains”) but it doesn’t work from Alexa Routines or via the Alexa app. Seemingly random devices are controlled then.

Why would it be different via direct Alexa voice control compared to Alexa app and Alexa Routines? I have tried “Forget All” in Alexa and resetting all my Alexa devices and nothing fixes this.

I was on the latest Home Assistant but have rolled back to 0.91.3 to see if that fixed it.

Any help appreciated!
