At a glance
Synchronization brings school or learning-platform data into Studyo. The system that owns a field should normally be where you correct it.
Understand the flow
Ask the school which sources provide accounts, section memberships, schedules and assignments.
Make corrections in the owning source, unless the school has arranged a local exception.
Allow the configured synchronization to run, then check its status in Insights.
Compare one affected account, class or assignment in both systems.
School data imports and assignment connectors are different processes. A timetable import succeeding does not prove that Google Classroom assignments have synchronized.
Update timing depends on the integration and its configuration; do not assume every change is immediate. Repeated local edits may be overwritten by the next import. Before deleting duplicates or reconnecting a source, follow synchronization troubleshooting.
