I pay for game pass ultimate and use it on my phone regularly. In the description when you subscribe to game pass it straight up says you can play on pc but then I go to play one of the exact same games I have been playing on mobile and they want me to pay again. It tells me I'm not subscribed but then I open the mobile phone app, which is on the same account, and it says I already have ultimate. This is literal false advertising and I need my money back.
