How to change "Shop Pay" to "Buy Now" on my payment button?

Topic summary

A user’s “Buy It Now” button is being replaced by an unwanted “Shop Pay” button on their product pages. They attempted to follow a solution from another community post that involved editing product-button.liquid, but cannot locate this file in their theme—only finding product-content.liquid instead.

Current Status:

  • Theme in use: Shopify Focal 12.4.0
  • Issue remains unresolved
  • User is awaiting guidance on how to proceed given the missing file

Key Challenge:
The previously recommended solution doesn’t match the user’s theme file structure, suggesting theme-specific differences in how payment buttons are implemented.
