As subject and attached image, I am building 2 Shopify Dev Stores and installed Shopify Spreadsheet Bulk Product Manager, but both of them Cannot Save Config Settings in the app.
Noted: I am using Shopify Spreadsheet Bulk Product Manager in my other site with Lifetime license and it works great!
Please help check and advise why the 2 Shopify Dev Stores Cannot Save Config Settings for the app?
