When studying Japanese, the wordlist “freezes” at certain words. After contacting the support, adding new words was suggested as a remedy. Unfortunately, that didn’t work. Let’s say the “freeze triggering word” is no. 150 in the list. I add 5 new words, but after I worked through them and arrive at 150, the trigger word, it’s frozen again. Forwarding doesn’t help, so far only blocking does.
So far, I can’t say if it are the words that causes the freezing, their row in the list, the frequency (as in “every eight word”) or sheer randomness.
I never had the problem on the Chinese version, which I use way more extensively . I’m on the Android beta, Android v.9
