I had to delete all my known words and start again with blue words. There is an option on settings to not create a lingq automatically. I lost all my data, but at least I can keep focusing on my reading, and do not have to click anymore to see the word’s meaning.
Calm down. It is a new interface give it enough time I am sure you will find a solution for your issues. You can do the same thing all over again but need to figure it out and just spend some time with the app.
