Google Home and Voice Match (multiple accounts)

[Scam]

(I figured this might be the best forum for this? Home forum seems a little DIY-orientated )

I have Google Homes all over my flat and do really like it. However I don't get all of the functionality because I have a GSuite account. It seems Google simply don't care about this and will never properly resolve it

But I do have other Gmail accounts. One thing I'd really like to do is get Keep integration working. So, my plan is;

1. Share my Keep 'shopping list' note with my *other* Gmail account (done, easy)
2. Add my other Gmail account to my Home(s)
3. Turn off voice match

I'm wondering if that would work; so when I ask Google to add something to my shopping list it adds it via my (normal) Gmail account. But when I want to use my GSuite Google Play Music subscription - will that work? Some of their guides suggest that you can only access your GPM library/playlists if you have voice match on?

Any thoughts?
