Nothing changed with how text frames are threaded in v16. Be sure that you have the Selection tool and click to select a frame. The inport and outport will be visible once the frame is selected.
If you can't select the frame, you won't see them. Is the frame locked? Is the layer locked? Is the frame on a master page? Does it work as expected in a new file?
