I’d like to add another possibility to this: (a feature of) the legacy frontend has stopped working on master, and its corresponding functionality has not been confirmed on the replacing MFE.
Right now we might be in this very situation for TPA hinted links in combination with the Learning MFE (see this thread): the feature appears to be broken in the legacy frontend, it might be fixed in the authn MFE, but we haven’t had any way to confirm that on Nutmeg since there’s no way to Tutor-deploy the authn MFE on Nutmeg. So right now, we really have no way of knowing if this will work in Olive.
