App Does not recognize voice

I’m trying to get Mira/Goose to respond to me. I see the Red microphone icon when I start a checklist, but it doesn’t respond to voice input. I say “check” but nothing happens. When the microphone is green, it doesn’t respond to “Hey goose” or “hey mira” or “hey Mirabelle”.

I have Samsung Android devices, a phone (SM-G991U1) and a tablet (SM-X200) and both seem to operate the same.
