Alexa app location

Hi all.

I live in Australia and I'm having trouble with Alexa skill becoming unresponsive after no specific time period.

I have to disable skill in Alexa and re-enable to resolve this.

I noticed, after looking for causes, my location in The alexa app on hubitat is set to
us-west-2.... I live in Australia.

I dont know if this is the reason, but just wondering if I could change this to Australian location ?

Any other Australian users out there that can help please.

Thanks in advance.
