phone won't enable "hey siri", but siri works fine manually
got a strange problem.
trying to enable the "update listening history" setting for Apple Music within the "home" app.
enabling it then asks to setup "hey siri" on the phone
however, no matter how many times i say "hey siri" it doesn't move past this screen.
the siri logo changes to show that it can hear me, but no matter what i do it won't progress.
siri works when i talk to it when i initiate it manually (holding power button), and my homepod mini responds to "hey siri" just fine.
any ideas what the problem is?
i've already looked at https://support.apple.com/en-gb/HT207489 and this hasn't helped.
i've never had the "listen for hey siri" optioned enabled, this is the first time i'm trying to enable it.
