If I log out of all the WMF sites (or just delete all my cookies), and then log into http://en.m.wikipedia.org, I am automatically logged into the other desktop and mobile Wikipedias, but not the other projects (Commons, Wiktionary, etc.). Even worse, if I log into http://commons.m.wikimedia.org, it doesn't log me into any other sites, even desktop Commons. Steps to reproduce: 1. Open a totally fresh browser (or delete cookies) 2. Go to http://commons.m.wikimedia.org 3. Log in 4. Go to http://commons.wikimedia.org Expected result: You should be logged in. Actual result: You are not logged in.
