Taking into account the impossibility to change something in the payment system settings on the site, the settings boil down to the following algorithm:
Go to the payment acceptance settings and add PayPal, set the billing address - skladusa.pp@gmail.com and save the changes.
Next, open in another browser tab for adding a store in the SkladUSA system (https://system.skladusa.com/web/ru/admin/user-shops/create) and configure the store parameters:
- Store type - tilda
- Store link (link to store home page)
- The field for the store name (not links) - numbers in the address bar on the admin panel(: https://tilda.cc/projects/?projectid=*******)
