Some iPad users may see an error prompt when attempting to pre-cache media files. The error details include, "System.IO.EndOfStreamException." This issue likely occurs when the network connection is interrupted.
Users should verify that all network whitelisting requirements are met. Any attempts of pre-caching media should be done from a reliable, uninterruptible network connection. If possible, stagger the pre-caching of multiple iPads so that network infrastructures are not negatively impacted.
