New words automatically moved to known

I use the LingQ app on my tablet. Sometimes, if I touch too close to the edge of the screen, it moves to the next page. When that happens, all of the new words that were on that page are automatically moved to known. The app used to prompt me if I swiped to the next page and there was still new words on that page. It doesn’t do that anymore. Anyone know how to fix that?

It’s not exactly what you were asking, but in the Settings, under Reader → General, there are the options “Tap to page” and “Paging moves to known”, among others. Untoggling either one of these would help avoid this problem.

As @fabbol mentioned, you can disable the “Paging moves to known” option under the Menu > Lesson Settings.
