safety within the buildings! No instruction in the Hand Book either. Had a big section Before!

The format for the attendance reporting in Member Tools is different from the report in Leader and Clerk Resources (LCR) to better fit the small screen on mobile devices. But the data to be entered is the same, or nearly so. The report is provided as a means of getting data into the quarterly report and will not include attendance reporting needs unique to specific areas of the world.
The default display is a list of unit members, or All Classes and Quorums, in alphabetic order. On the default screen and just below the search box is the title "All Classes and Quorums". This lets you know what members are listed. Below that title is a help instruction that states "
Filter classes using filter icon above."The classes can be filtered using the three bar filter icon on the right at the top of the screen in the blue report title bar. Note there is a filter for Sunday School.
It is the responsibility of the organization secretaries to record the attendance as mentioned in
General Handbook, 8.3.4, 9.3.3, 10.5, 11.3.3, 12.3.3, 13.2.2.1. Local requirements for attendance you mentioned would have to be handled as directed by the area or local leaders outside the application.
The Member Tools attendance report only provides the ability to record attendance for the current month (5 Sundays) while the LCR attendance report provides the ability to record attendance for earlier dates.

A little note:
Rows attendance at home; for each class that is happening reported.
Rows for each class; in person classes in the building.

This also required for safety in an emergence by law.
Collecting of outline for classes as they happen to send to those not attending.
Activating close captions for the hard of hearing in all meetings.
