On my profile I find:
" Pokalbiai / Pamokos / Žinutės / Etapai / Forumai / Sienos žinučių pranešimai / All Requests " instead of the German translation. It was correct this morning.
More strange is it on the Exchange page:
" Gespräche / Lektionen / Nachrichten / Meilensteine / Foren Beiträge / Benachrichtigung Rosen / All Requests / Open Requests".
Then I opened a second tab with the Exchange page and it became:
" Gespräche / Leçons / Nachrichten / Evénements décisifs / Posts du Forum / Notifications de Roses / All Requests / Open Requests"
A refresh of the page changed the result again:
" 会话 / 课程 / 新消息 / 已知的词汇量 / 论坛主页 / 查看内容详述: / All Requests / Open Requests"
I think this is a new feature LingQ offers to encourage us to learn more languages
I also noticed this by accidentally keep pressing the lingQ icon at upper-left corner, which equals to keeping refreshing the same page. I noticed the languages below Filters also changed every time when I refreshed the page.
