I have a ridesense cadence sensor which has been paired to a 910XT. Sensor is about 3-4 years old. Two weeks back it stopped working so I replaced the battery and it worked for my next ride. Since then it hasn't worked. The red and green lights come on when initially cranked but no information is recorded by the 910XT. Have tried re-syncing with 910XT but it is not finding the sensor. Any suggestions in how to re-sync would be much appreciated
