We're on 3.5.2.
Can someone with 3.6.x /3.7.x with the Turnitin integration check this for me before I list it as a bug...
Create an assignment and under submission types select "online text" only AND enable Turnitin. Save.
View the assignment as a student.
For us the all the information about uploading files to Turnitin is displayed (see screenshot). This is confusing for students because they are not required to upload any files.
