Airplay icon disappeared from iTunes 1.12.6.3
Running iTunes under Windows 10 on a Toshiba laptop. Airplay icon has disappeared from iTunes menu. It appears briefly when first opening iTunes, then disappears. There is nothing wrong with my network, because i can use the equivalent of Airplay in the Spotify application. Airplay was working with iTunes on this computer. iTunes has been updated to 1.12.6.3. Do I have to uninstall/reinstall?
