1030 plus and heart rate monitor fail

Last week my Livlov chest strap worked fine with my Edge 1030 plus and has done for a few years.  Last battery change around 6 months ag.

I done an update around 2 weeks back on the Edge and the last ride shows a pulse in the setting menu but will not show stats in the ride menus.

I changed the battery de paired and repaired but it wont actually connect and show heart rate???  Just about to go riding again :(
