when I updated my ide and opened a new basic activity then it is not working and giving the message that" design editor is not available" on the screen and on the downside window the message" No cache version of com.android.tools.build.gradle:3.6.1 available for offline mode" is showing.
and these all are blocking my activity_main window to design and make the layout of the app and also I am not getting the "text" and "design" window of my activity_main window.
