Edit Variables in a browser does not work!

Google Cloud Nightscout » Update variables in a browser

If choosing “Edit variables in a browser” from the menu brings up a dialog directing you to press enter to proceed, but doing that takes you back to the main menu, you will need to update the platform.

Please use “Update platform” from the Google Cloud setup submenu. Then, please close the window when directed and open a new one.
Now, edit variables in a browser should work fine.
