In 2013 if you create a custom master page and upload it with Design Manager and it does not contain the left nav menu placeholder (see the blog article here) the "Add an app" function breaks. According to that article (from nearly a year ago) Microsoft was working on a fix. Does anyone know if it's been released yet? I can't find definitive information on it beyond that article and a bunch of people on other sites referencing it. I tried looking through the CU descriptions, but I'm not sure exactly how MS would phrase such an issue.
If there is no patch for it, does anyone know a work-around other than the one in the article? I would like to be able to use completely custom navigation if possible.
