We are using odoo.sh and we are importing close to 15,000 products.

And in the existing fields of web_descrption in product.template table the type is html

Which doesn't support multilanguages and takes only 1 language while importing through an excel.

We don't want to go for any third party plugin. It's hard to believe that a platform like odoo doesn't support product description for multi-language. Is this a bug from their end? 

Would be great to find a solution or any links that might help us.
