First, I'm a full stack developer, don't tell me what it costs to make an application because I already know.
Second, they can take as long as they want to implement it, what pisses me off is that when I bought this application one of its main functions was "FULL HELLO SUPPORT" and this is not so. As a buyer, I have the legitimate right to complain that a product is not what its advertising said.
If you don't want to complain about having made it clear that before you had to set the password... When they enable it, I will thank them, but let it be clear that it is understood that this function has already been implemented.
