I have noticed that i can only see how much gold my duos parner has when we go to battle and not in the buying phase.
I use be able to see it before but not anymore it is important to see how much gold they have epscialy for passing with murlocs.
But in general i feel i need to be able see how much gold they have idk if anyone else has noticed this.
i have the same probleme … have you find any solution ?
Not yet unfortunatly i just reported it here so that the devs just are aware of it and can hopefully fix it in a future patch 
This bug is very annoying. I hope they will fix it soon.
They introduced this bug with the first balance patch they did. It’s not important enough for them to fix atm.
it is now fixed for me !
