Additionally, I want to add that for the support agents is extremely important to be able to know well the structure of the products and be able to use the code inspector. This will solve problems very quickly, instead of a multi-day correspondence to gain access. In 90% of cases, access is not required and problems are solved very quickly if you use the code inspector.
This topic is proof of this.
This topic exists 2 days. Of them to solve the problem it took two hours, taking into account the delay in the correspondence. And clean time to solve, without delay in the correspondence - 15 minutes.
