Ay, frustrating yun talaga! Okay lang, try mo ulit pero mag-screenshot ka ng error message para sigurado kung ano exactly ang problema, minsan kasi ang website ng SSS ay buggy talaga, lalo na kung maraming nag-access simultaneously. A few of us tried calling their hotline directly instead ng purely online kaya mas mabilis kami naayos, so maybe that's your next step if ulit-ulit pa rin the same issue, or visit the nearest branch pa rin to clarify personally what they need from you. Fingers crossed na ma-process na ang maternity benefit mo soon!
