Retroachevements - impossible to log in

Hello everybody I installed lakka 3.2 on a rasp 3b+, everithing works fine except retroachievements. I created retroachievements account and inserted all the login infos in the achievements setting menù. Once I enter in the game, in the quick menù I select achievement and Lakka says that im not logged in. In achievement settings menù I can’t find nothing like a submit button to test if I’m correctly logged-in. Is it a bug or I’m missing something obvious? I tested my account on retroachievements website and its ok do you have a solution? thank you guys
