Maybe you can help me mr lvl 10.
I'm having the same issue with my iPhone 7. Can't find my device on iTunes. On top of that my phone is only asking to allow device to access photos and stuff. Never asks to "trust" computer
I have windows 10, a laptop that was purchased couple months ago. iTunes running 12.5.3.
Possible solutions I found online, I tried them all.
Restart laptop and phone. Tried different USB ports and cord. (It's connected seeing it asks to access photos at least and charging). Reset privacy settings on my phone...reinstalled iTunes. And some other stuff to no avail...
