Assignments for media upload do not work

[Splines]

Upon creating a new medium, a dialog opens that allows to also create an assignment for that medium. However, this checkbox cannot be activated (the Submit button doesn't do anything).

Seems to be working again. Did you do any updates since yesterday? I still use the same setup, haven't cleaned up cookies or cache. For the exercise I uploaded yesterday it didn't work.

No, the last production release was last week. So maybe it was a problem only in a very specific scenario ?

Not sure.. it happened several times over the last weeks, whenever I uploaded a new exercise sheet. Maybe I didn't even try to activate the box for the assignment yesterday, assuming it wouldn't work anyway. Can't tell for sure, to be honest :)
