Changing Paypal Address Used to Pay For Shopify Services

[J_U]

Hi there. I have gone through multiple threads and I could not find the answer to my question.

I initially began my store and with one paypal account tied to my account. Let's call it aaa@paypal.com. However, I have now created a new paypal account specifically for my store which is also receiving all my payments from the shop. Let's call this new paypal account bbb@paypal.com. The issue is that on the shopify default payment method menu, I can't find any way to delete or edit my old aaa@paypal.com account so I could enter the new account bbb@paypal.com. Any help or guidance on that would be greatly appreciated.
