Microsoft has addressed the 'ring after pickup' bug in the Metro-Style version of Skype for Windows 8.1, a week after remedying the issue in Skype for the Windows desktop.



From All About Microsoft:

The issue doesn't seem to be entirely fixed, according to a March 10 post on the Skype "Garage & Updates" blog. But it's better than it was, officials said, with the annoying ring stopping "much faster" with "Skype for Modern Windows 2.6."
