iPhone won't erase all content and settings
I'm trying to erase everything from my previous phone. Not even the last phone I had but two phones prior. When I click on the Erase all content and settings it has a message that says Documents and data are being uploaded to icloud.
I have icloud drive shut off on this previous phone but the message freaks me out. This previous phone; the iPhone 6S hasn't been used since 2017(and have had another phone afterwards; PLUS I just upgraded to the phone I have now, just a few days ago.) so not sure what documents might be loading.
Is it safe to allow it to erase everything?
