It should take around 10 minutes to update 30 Classpads. If the update fails, try again. Occasionally, some devices may not update properly on the first attempt — for example, only 25 out of 30. When you try again, only the remaining devices that still need the update will be updated, in this case, the other 5.

If, after several attempts, not all devices update correctly, please contact us at [email protected].
