Connect - samsung multiroom

[user-removed]

Hi!

I'm having some trouble with my old account, to get it connected to my samsung multiroom speakers. I have access to two premium accounts, but the connect function is only working on one of the accounts. I can see my multiroom speakers on both accounts but it's only possible to make it work/connect with one of the accounts.
It's on the same phone/device it's working/not working on as well.
