EDU Publishing House Diagnostic is the official application for quickly sending diagnostic data to the EDU Publishing House support team. The application automatically identifies on the phone the EDU Publishing House applications compatible with diagnostics, and the user chooses for which applications he wants to upload diagnostic data. After selection, the application prepares an archive with the available diagnostic data and sends it securely to EDU Publishing House, using the upload code received. Sending is done only at the user's initiative, directly from the application. An internet connection is required for operation, and the maximum size for an upload is 10 MB.
