Unfortunately I have an assignment in a course where I don't see the submit button although I am not using the "switch-role" capability.
I think I checked everything: permission, role, group, dates etc.
I can import the assignment into an other course with the same result. That is really strange.
I changed multiple parameters in the assignment with always the same result -> No submission button.
I used different users with different enrolments -> No effect
Unfortunately it would take too much time to check the code, because I am not a good programmer.
Well, I hope that I will not run into that problem again with an other assignment.
