If you have a multisite installation, make sure to configure the price scope before you create your shared catalogs. The price scope can be set to
Website. However, it can be set only at the beginning of the setup process. The Website chooser appears during Step 2 of the shared catalog setup.
Configure the price scope
On the Admin sidebar, go to Stores > Settings > Configuration.
In the left panel, expand Catalog and choose Catalog underneath.
Expand the Price section.
Set Catalog Price Scope to

Click Save Config.
