Nintendo Switch update 12.0.3 is still giving these problems to some users

You probably remember that Nintendo Switch update 12.0.3 was released this week and then withdrawn a few hours later by Nintendo. Finally the company re-distributed it to users, but it seems that this patch is still giving problems. There are users reporting that they can not download from the eShop the games they have already purchased. They get the error code 2123-1502, which cannot be solved even by following the steps specified by Nintendo. Customer support has confirmed that Nintendo is assessing the situation and are aware of the problems. Some gamers mention that SAT has helped them reset their console’s cache over the phone, but it has not been confirmed that this resolves the error. There are also users indicating manually changing DNS settings as a solution, but we have also not been able to learn that this is helpful.
