Hello. Can you please clarify if it's true that now the developer cannot respond to customer comments? (from December 16, 2020). In this case, can a regular user respond to user comments, for example, on behalf of a developer? If so, do you need to make a $50 purchase on Amazon every 12 months and will this answer be visible to all other users?
And the most important question: if the seller responds to user comments under a regular user account, will it comply with Amazon policies?
