Got a brand new XZ3 a few months ago, updated to Android 10 and since then I noticed  since security update on Android 10 Build No. 52.1.A.3.74, I was unable to switch Hey Google voice match back on - it seemed to turn itself off?

Factory reset, cache/data clear, uninstall updates on Google app and software repaired the phone but it just says 'Something went wrong. Try again.' when I try to turn on Hey Google.

Since then, Sony support have just sent me running in circles with resent troubleshoot email templates telling me to factory reset again.

Loads of other XZ3 and XZ2 users mentioned the issue here, is anyone else having it and have you had any luck talking to Sony or Google about it?
