iCloud upload won’t load to factory reset
I recently got a new phone and am doing a trade in for credit. I need to factory reset my iPhone, but when I click “Erase All Content and Settings” I get the message “Documents and Data are Being Uploaded to iCloud.” I would like to keep all my iCloud data, so I clicked finish uploading and erase. It uploads to 67% and then stops and I’ve tried this multiple times. Any help?
