Answering several angry emails from school managers at 10:47pm saying pretty much the same thing:

That new feature you wanted your teachers to have doesn't work on an iPad and I can see that all of your teachers are just using iPads at the office. As explained during training, the iPads cannot use this function. Please have the teachers use the notebooks or desktop computers when accessing this function.

I've said the same thing and wasted boatloads of time verifying in the server access logs that people:

  1. have access to the function
  2. are just using iPads (which is great in theory, but not in this case)
  3. are not understanding directions

Alas …
