Where is Aa/Яя button?
I try Dolphin, Chrome and LG browsers on Mobile & Firefox, IE & Chrome on Laptop?
After you begin the lesson you should see it on the top left, right beside the "tips and notes" link.
I have heard that the mobile version of the site does not show it to you. You should switch to the full version and change that setting there.
How would I know? I only have an iPad. But it does not ue the mobile version of the sait. Not that I know of.
I wonder why this setting is not persistent. It sticks for a while, but every once in a while it switches back to latin and I have to change it back. It seems like it should be a setting that stays until I specifically switch it, like with the audio settings.
Oh my God! "After you begin the lesson" was the Key. Thank u WanderingMonk. In fact, you do not need to go to a desktop to change this preference. It is just the same if you go to "View Full Site" in the options and start a lesson. The button Aa/Яя appears (but if you use a smartphone like i do, you´ll probably switch back or restart the Duolingo web page for a more confortable view.
