Doesn't save my progress

Hola, me encuentro realizando el curso online de Simulink Onramp desde la web, pero me he encontrado con un error en el que no guarda mi progreso en la sección de Sistemas discretos, terrmino todo y solo me carga al 50%, y ya lo he realizado infinada de veces pero sigue igual. Solo me falta eso para obtener mi certificado de finalización,

Agradezco su pronta respuesta.

Hello, I'm currently taking the Simulink OnRamp online course, but I've encountered a bug where my progress in the Discrete Systems section isn't being saved. I finish everything, but it only loads at 50%, and I've tried it countless times, but it's still the same. This is the only thing I need to complete to get my certificate. Thank you for your prompt response.
