iTunes doesn't recognize iPod nano 7
I bought an iPod Nano 7 online and it synced the first time. The second time I went to sync it, iTunes didn't recognize it. I uninstalled iTunes and did all the recommended options and couldn't fix the problem, so I returned the ipod and bought a different one at Walmart. The exact same thing happened, syncs the first time, then iTunes doesn't recognize it. I've tried everything. My computer syncs my iPod touch just fine. What to do?
iPod nano, Windows 10, Nano 7th Generation
