When my learners log in to CoSpaces on the Oculus Go it is very difficult to see the letters as they are typing them. The background of the text field needs to be more opaque. Their email addresses (logins) are long and parts of it cover the white space in the background scene. Since you are using white text, it blends together with the white area of the background and is difficult to see. Make the text field more opaque or changing the text color to black would make it much easier to see.
