We are currently experiencing an issue where students are not receiving email notifications when a teacher posts an announcement on Canvas. As a result, students remain unaware of important updates until they manually log in to their portals. This delay is creating challenges for our teaching staff, as timely communication with students is being affected.

Could you please investigate this issue and advise a possible solution?
As far as I am aware, I have already reviewed all relevant notification settings at the admin, student, and trainer levels. All the required toggle buttons and notification preferences appear to be enabled.
