How do i use a Weebly theme on an existing square site?

[Mariahkann]

YouTube has a ton of tutorials on creating a new store with a weebly THEME, but the format looks different than my existing one. Please help.

HI, when Square obtained Weebly 2018 the themes were discontinued.  No themes, no designer pre-made templates on Square.  There are 2 formats, Retail or Menu.
