Accessing HBO Max

So, I have figured out how to talk into my remote, and pull up the HBO Max account, I have logged in.  Now the dilemma, how do I select which profile to access.  It seems to defailt to the main profile, and I want it to default to another.  Hint, I borrow my daughters account, she has created a profile for me, works fine on the app on my iPad, not so fine through this 'third party interface'.  Any suggestions?
