Some testing notes: As admin on web, go to Site administration > Mobile app >Mobile authentication There you'll be able to set the "Minimum app version required". Format can be: 4: same as 4.0.0 4.1: Same as 4.1.0 4.1.1: Same as 4.1.1 In the app: login on a site. On the web, set a greater version that the current app: i.e 4. Close and open the app again. Check you're logged out, a message should be displayed indicating the version. Check the Download button goes to the correct market app. Click on the site to login again. Check you're logged out, a message should be displayed. Now navigate to settings > Syncronization. Try to sync the same site. and check you're logged out again. Now repeat the test with a version lower, i.e 3.5. Check it does not logout.
