I Miss Calendar and Email Notifications on My Vivo V40 Lite Despite Settings Fixes

I’m experiencing a serious issue with my Vivo V40 Lite that’s affecting both my personal and professional life. Important notifications like calendar alerts, reminders, task updates, and emails simply do not appear. I’ve missed multiple important events and deadlines because of this. Even after toggling notification settings on and off several times, the problem still isn’t fixed.
Sometimes I hear the notification sound, but there’s no actual content—no pop-up, no preview, nothing. This makes the phone completely unreliable for managing daily tasks. I bought this phone expecting it to help me stay organized, but instead, it's causing chaos.
I need urgent support from Vivo to fix this issue. I can’t afford to miss critical updates just because my phone decides not to show them. Whether this is a software bug or a configuration issue, Vivo must provide a solution immediately. Please treat this as a priority—this is not just an inconvenience, it’s a major failure in basic functionality.
