iOS 8.1 and iCloud Issues

Since upgrading to the first beta of iOS 8.1, I started noticing that a few apps were randomly hanging or crashing at launch. I thought that the problem would be fixed for the public release of iOS 8.1, but soon after updating to the stable version, it occurred again. – MacStories
