Tap to translate doesn't work anymore as it used to be. The idea of tap to translate was to have an INSTANT translation of the copied text. Now, it makes no sense; you have to clean the past translation and past the new one. Thank you, I also know how to use standalone apps. And "translate" option in the context menu for selected text does not appear everywhere, even not in the native Googke apps like Gmail. Other app I use still do it properly. So, it is not a system limitation.
