Homesharing does not work iTunes 12.2.2
I realize that this is probably a question that has been posed before repeatedly. My issue is a little different from those I have read. I'm trying to use Homesharing on iTunes 12.2.2.25. I have two Windows 10 machines each running that version. Homesharing is turned on for both machines. They are both connected to the same wireless network (a router I recently restarted to ensure that wasn't the issue).
In the upper left, just under the menu bar, are the little icons for music (eighth notes), movies, TV shows, etc. I click on the 3 dots next to them and get a drop-down menu that lists several other items with checkboxes next to them. The Homesharing icon is at the bottom of the list (the little house with the note inside). It is checked, but it DOES NOT appear when the drop menu is gone. When I click the checkboxes next to each of the other icons, they appear in that bar. Not so with the Homesharing icon. It does not appear and, as I understand, I need that icon to appear to access libraries on other computers.
Interestingly, I just checked my MBP running Yosemite and the same version of iTunes (12.2.2.25) and it suffers from the same problem. So this is clearly an iTunes issue as opposed to something having to do with the OS.
Anyone know the solution? Much appreciated!
