Is anyone else trying to go through the courses? I’ve had a couple videos with the sound cutting out, a few quiz questions that are ambiguous, etc. The problem I have now though is in the “Understanding Tags” topic. There is a question asking about the data quality of a tag in the challenge project. See the attached pic. The tag quality is clearly “Stale” but the quiz is rejecting that answer. Anyone see what I’m doing wrong? Has anyone else gotten through these courses successfully? Thanks!

Hey Joe, Judging by the red overlays on all the components on the window, it looks like there might be a different issue, like a faulted OPC UA server or something like that. I would recommend looking in the gateway console under the configure tab of the gateway webpage. It might be able to give you some more information as to what is going on.
