There is a document size limit of 15MB in training and improvements modules. When users try to upload the oversized doc, there should be an error message about the size of the file rather than, just lack of success to complete the task. We have this issue sometimes with uploading docs to Improvement records, or with uploading training evidence to attended training. It does not successfully close the action or record the training attendance, but it is not clear that the size of the document upload is the reason we are unable to successfully complete.
From a promaster point of view, this can be a serious problem for engagement with the system – when user is trying to close off an action or mark an attendance and it is not clear why it won’t go through… So they say “WHY won’t it just WORK!!” This is where we lose people, and they don’t want to use the system.
