flnative,
The sorting of articles issues is a known, obscure, problem that affects very specific configurations of sites. We have a fix implemented for the upcoming v5.1 release later this month, just so you know.
Regarding the mobile view, can you test on this site and/or our
Demo Site
and let us know if you have the same issues here/there? We do test in mobile browsers (android, ipad, etc) and haven't seen or heard of this problem from other users.
We'll gladly look into things further, but would love to know if it's specific to your site or something on others as that will help narrow things down.
Thanks,
Alex
