Upgrade to 8.3 at the time of backup I had 1.2gb of used Other Data. Hooked up the watch, used it over the weekend and now up to 89gb of Other Data.
Turned off the Watch, and restarted the phone but I can not find anyway to remove the Used space. Deleted my main Email account but that did not free up any space.
Looked in Setting - Have 29gb of Video and other apps are around 500mb. Not enough small apps to make up 89gb.
The Apple rep requested I restore from my Upgrade backup. Has anyone see this happen?
