Students cannot deliver or download pdf. Is there a reason that this happens from time to time?

I recently started using hand and quality. I had a few cases in the past where students got an error message when you try to download pdf assignments. The last two days, I had submit them their work, the students, so I got a message "not delivered". The file is there but cannot be opened. Is there a fix on our end?  I tried to reinstall the application on the iOS device.

Network conditions generally make the such problems difficult to diagnose because any network or machine between you and Apple servers could be the cause of the problem. You may be able to reduce the problem of:

  • check the status of the Apple servers to http://www.apple.com/support/systemstatus/
  • Use an application or a service like speedtest.net to test the performance of your local network (select a test host near San Francisco, CA)
