HomePod mini unreachable / Home Hub not working
I've had my HomePod mini for 2 days and I am unable to get it to work as a home hub or set up any automations.
The home app on both my iPhone and MacBook has a warning saying "No Remote Access" and unavailable appears under the HomePod.
I can use Siri and stream music from Apple Music from the HomePod, however I cannot transfer calls from my iPhone to the HomePod or initiate or answer a call through the HomePod with Siri.
I followed the troubleshooting instructions which were to reset the HomePod and go through the setup several times, thinking I did something wrong, but this was no help.
I attempted to have a support call but was not able to book one as I am currently residing outside of the US. Any help to resolve this would be greatly appreciated.
