Fabio, I am in almost exactly the same position. I was having a great experience with Premium, migrate the business, then everything in chaos with the migration. The cost of the product is nothing compared to the lost time! EN Team need more content available on how to use Tags in Business Version. They claim in promo videos that they have tested this product inhouse and would not share the product if they did not use it. Surely they have had the same experience as so many people in the forum.
