Google & YouTube

So I attempted this morning to add this. Two issues. First, it created a brand new account under my main google merchant center login. This is not what I wanted. I am a trusted store, have local and Buy on Google set up under my other account. Why would I want to start from scratch. The other issue is that I have sub-accounts under my main google merchant center account. It allowed me to select from them, but didn't list the actual sub-account I needed to connect to. It only listed three of the four sub-accounts I have. I have no idea why it didn't list them all. We do live shows every month and have over 85,000 followers on Youtube. I think this could be awesome if you can help me to get it to work and I would change my review to 5 stars.
