-Syncing may fail after a period of time, likely around 30 days, due to the fact that your Actions on Google app is technically in testing mode and has never been published. Eventually, it seems that the test expires. Control of devices will continue to work but syncing may not. If you say "Ok Google, sync my devices" and get the response "Unable to sync Home Assistant" (or whatever you named your project), this can usually be resolved by going back to your test app in the [Actions on Google console](https://console.actions.google.com/) and clicking `Simulator` under `TEST`. Regenerate the draft version Test App and try asking Google to sync your devices again. If regenerating the draft does not work, go back to the `Action` section and just hit the `enter` key for the URL to recreate the Preview.
