I was using alfred netease workflow for years, but after I changed a new laptop and downloaded the workflow, it does not work anymore. Finally I found out the reason and came out with a fix.
It turns out that my netease music is in English version and the workflow identifies those menus in Chinese, for example :tell menu "控制" of menu bar item "控制" of menu bar 1
So the fix is to change those names to English according to the actual menu and menu items names, for example tell menu "Controls" of menu bar item "Controls" of menu bar 1.
Hope this would also help you.
