I just upgraded from 7.3 to 7.3 SR-1 and my Home page is now blank and so is the Courses tool.
If i go to the library and then exit, the Home screen will load, but it does not load with a refresh boot, and the Courses tool will not load any content at all no matter what i try.
Running MacOS Sierra 10.12.2 on a 27" iMac Retina 5k
No problems prior to updating to SR-1
