It stopped working properly since Android 10. Previously the pop to translate icon showed up only for a bit of time when I copied a new word to the clipboard. Right now it's visible all the time and it occupies the space on the screen even when I don't need it at all. EDIT Now after recent updates the UI got even worse and a lot of features were hidden. You need to scroll down to see the translation for longer texts. Whoever approved these UX changes should be fired lol. What a shame.
