Some LingQ yellow words remain yellow even after being marked as “known”; they only revert to their normal state after refreshing the page.
I have seen same problem. The problem is also with marking word to be known, or delete.
I use PC with Firefox, and Win11.
I use PC & MAC ，chrome or Firefox same problem. PC win11，mac macOS Tahoe.
@len1984 Thanks. I reported this to our team. We will have it fixed.
