Sometime last week I changed the theme to the full version on my phone to view something that doesn't show in the mobile view. Then when I was done I changed the theme back to mobile.
Later I logged in via a PC, and it switched that one to the mobile theme. So I choose full version at the bottom - then the next time I log in from my phone it goes back to full version. It's now a constant back and forth whenever I change devices.
Ack! How do I stop them from fighting each other? This has never happened before.
