How to disconnect old store products from new POS app?

[happydino]

I used to be an owner of Store X using Store X’s email address. I am not longer associated with Store X. I started a new Store Y and I logged in to Shopify with my Store Y email. For some reason, I can still see the products from Store X on my Shopify POS app. How do I disconnect Store X from my Store Y POS app?
