It sounds frustrating, especially since it worked fine before. If the CSV is showing the correct prices in the preview but not updating them after the import, it could be a caching issue or a slight error in the CSV format that’s not obvious at first glance. First, try clearing your browser cache or checking in an incognito window to see if the prices have actually updated but just aren’t showing due to caching. If that doesn’t help, double-check the CSV file to make sure the prices are in the correct columns and that there are no extra spaces or formatting errors. Sometimes even small things like that can cause issues.
I’m using to import data the same file that shopify export. Only change values.
After the update, all remains the same, both the admin and the site. I should point out that in the Shopify preview (before updating the file), the prices appear changed,
