Activity not uploading.

I'm running software version 12.72 and yesterday updated to IOS 26.0.1.  I did at least 4 workouts perfectly fine on the new IOS and everything transferred to Garmin Connect just fine.  This afternoon at about 3:30p EST I did a 1 mile walk with my pet and came home and looked for it in Garmin Connect and it's not there.  It's showing in history on my watch like it's supposed to be but will not upload to Garmin Connect.  I even tried to do the transfer the old-fashioned way by trying to sync directly with my watch and computer and Garmin Express to get it to upload to Garmin Connect.  It says last synched at 4:28p, but the 1 mile walk is not showing up.  What gives????????????????????
