How to activate the move alert bar on watch face?

My previous Fenx 3HR would have a red move bar appear on the edge of the screen if I hand't moved for a period of time. The red in the gauge would continue to increase until I walked for a while. The first time the move alert gauge would appear there was also a move alert notification and vibration. Now, on my new Fenx5s, all I get is the move alert notification which then disappears but no move bar appears on my screen. I can't see how to enable that? It was a great visual reminder to move. Can anyone let me know how to enable this feature? I have move alert switched on in settings. I've done a search and seen another thread on this but it didn't seem to resolve the issue. Thanks!
