New Photos app stuck on welcome screen
I used the new photos app weeks ago and it was working fine, Today, I opened the app, and I can't get past the welcome screen. It is not frozen. I can still open and close the virtual tour. However when I click get started to go into the app, I just get the spinning wheel. I left it there for hours and still no progress. What is it doing?
MacBook Pro, OS X Yosemite (10.10.3)
