**Describe the bug**
When trying to enable Chime on HomePod I get Could Not Complete Operation.
**Debug Output**

**To Reproduce**

Steps to reproduce the behavior:

1. In Home app, select doorbell camera
2. Click Notifications
3. Select Chime on HomePod

**Expected behavior**
HomePod should Chime

I noticed this was mentioned back in August and I did comment there however that is a Closed issue. It stated this should be sorted once iOS 14 is out of Beta. As iOS 14 is out of Beta and I am still not able to enable Chime on HomePod I’m just checking if its an issue with the plugin, Apple or my setup. 

Thank you
