Question: How To Synch MP3 and MP4 Files from PC to iPhone?
I am trying to sync MP3 Audio and MP4 Movie files from my PC to my iPhone 7 Plus. The iOS is up to date and is running 11.2.6. I previously had some MP3 files that I copied from my PC to my iTunes account and could "Sync" them to my iPhone by using the "Sync" feature. I uploaded some movies in MP4 format to my iTunes account this weekend, however now everything has been removed from my iPhone including the MP3 files I had on my phone for the last year.
I think I have audio MP3 files and video MP4 files in my iTunes library.
All I want to know is to transfer/copy or sync the content to my iPhone.
The "Sync" button/feature is not working and nothing is synching.
iPhone 7 Plus, iOS 11.2.6
