I found a hole on add product. If the same link is filled twice it will not take it right. But if i made a single string different, it still able to take it. For example: 1. https://example.com https://example.com - This will show product already assigned But if just adding a simple string at the end 2. https://example.com/ https://example.com/ - This will able to fetch data for the product and can be assigned
