Beside disputable changes in UI, it doesn't work any more for me. Sony Xperia XZ1 here. For example in WhatsApp when I copy a text, the usual balloon doesn't appear any more. Via the contextual menu after a long press I can choose "translate" for it to appear but then I have to manually paste the text and press to translate. If I choose to show the floating icon in the settings, this is permanent and intrusive, and I have to still paste the text I manually copied in to get my translation.
