Tenor frames and s10 voice assistant. Changing from bixby

[Glenn St Clair]

Detailed description of the issue and steps to reproduce

I cannot change the voice assistant away from Bixby. I want to use google voice assistant but it does not change. Bixby is **bleep**. Have googled everything and there are some steps about choosing the assistant in the Bose music ap. But the settings are non existant for me. 

Thanks for any help

What environment do you experience the issue in? (e.g. noisy office, quiet kitchen, etc.)

When did you start to experience the issue? Did it work correctly previously?
