Edge 1030 Speed Sensor

I have just replaced my 1000 with a 1030 on its own as I already have the various accessories. I have successfully paired Di2, Cadence, & Heart Monitor, but cannot get the Speed to sync, despite it being an ANT component, with a new battery, the wheel turning and the 1030 next to it!

Does anyone have a solution or recommendation. New Sensors at circa £34 which I'd rather not spend as the Ant Speed Sensor I have should be compatible & work

Thanks Will
