Alexa Responds I’m not quite sure what went wrong, after restart

As topic, Alexa responds " I’m not quite sure what went wrong with " when asked to perform an action. This primarily happens after restart of HA. Using HA Assist voice command works fine.

If I use the web interface, logout of home assistant cloud / link (Nabu Cassa) , then log straight back in it all start working again. (Logging out and back in of the cloud / link through the Android app doesn’t seem to fix the issue).

Has anyone else experienced this? It seems to have got worse since Alexa went to Alexa+, but I have no solid evidence for this.

Any troubleshooting steps I can take?

Thanks.
Matt
