Intensity minutes from my Garmin 830 bike computer were not recorded on my vivoactive 5 or Garmin Connect on my PC

Intensity minutes from my Garmin 830 bike computer have always been reflected both on my vivoactive 5 watch and Garmin connect app.  Yesterdays ride did not populate any intensity data even though I know there should be quite a few minutes of intensity and vigorous activity.  How can I restore this data?
