Fixed - This issue has been resolved and is being released in the 04/01/2022 web update.
Known Issues - Sections are not displaying correctly on the Teacher Attendance page in the following situations:
1. Teachers with multiple sections per period
2. Databases using the Teacher Multi-school feature
Programming is working on this now. We will update this post when the issue is resolved.
Users may add themselves to this Aeries Idea to follow the progress of the fix.
Our LEA was able to use a workaround for now: Attendance by Photo-Old
Teachers with multiple sections per period have been able to submit attendance (so far).
