Can't even synch a new AppStore app itself
Synch apps worked for years for me. I have about 300 apps synched so far. After downloading 11.0.1 synching apps stopeed working on my mac mini server with Snow Leopard 64 bit server. Strangely appstore app and itunes app disappeared from my devices. An attempt to get the newest 12/26/12 AppStore app failed at synch app stage falied together with other apps hanging after sysnc either in Will Remove or WIll Install.
Synching of books, photos, podcasts, iTune university still works fine. Please fix the app synching bugs.
