I have the same issue for the past several days. I guess I will be updating iTunes from 220.127.116.11 soon. Such a pain to have to update each iOS device individually.Speaking of apps, it appears as though Apple has turned off he spigot for those of us who were updating our iPhone and iPad apps using iTunes 12.6. For the past couple of days the apps will show as new updates but will not download. They appear to be downloading, but the circle doesn't appear and they don't download. Tried this on two iMacs with different operating systems.
