Data not saving - not sure why

I have an app that teachers in my school can use to write reports for parents giving student progress. There are dozens of drop downs and a comment box on each of 4-6 pages where the teachers enter the data.

I set it up to autosave (binding each item) and during testing I found no issues.

I few days ago when they started working on these reports, all seemed fine. Now I am getting emails from a couple of the teachers stating the data is now gone from several of the students.

The database logs do not show the data being saved from a few days ago, but today it show their enteries.

Where should I look? TIA

I have this issue a bit with the rich text input…

the issue is usually

  1. user doesn’t save it
  2. it saves on a thing that doesn’t exist
  3. the thing it saves to has the wrong linkage so isn’t looked up correctly later

Is it possible they’re editing offline? I may be stating the obvious but a connection is required for auto-binding to work and can be unreliable with an unstable connection.

Would it be possible to add a Save button instead of auto-binding?
