Apple has pulled the iOS 9.3.2 update for the 9.7-inch iPad Pro
and is working on a fix. Apple provided an updated comment to
iMore on the issue:
“We’re working on a fix for an issue impacting a small number of
iPad units that are receiving an error when trying to update the
software,” an Apple spokesperson told iMore. “We’ll issue an
update as quickly as possible.”
Seems odd that it took so long for Apple to pull this.
