iPhone 8 Plus issues with iTunes
I have been unable for several months to use iTunes with my new iPhone 8 Plus. I have updated iTunes, updated the OS on iPhone 8 to 12.1 and searched and tried what fixes are available. I have no issues on 2 of my Windows 10 PC's running the same configuration to my iPad. I cannot remove iBook files, add music, movies or TV shows on iPhone yet have no issues on iPad.
Considering going back to an Android phone as I never had an issue.
Any help?
