Custom Heart Zone data on Inspire 3 is not used on reported data

UPDATE: I figured it out.  Ignore this posting.  (Now I can't figure out how to delete this posting!)

Original  posting: I have a Fitbit Inspire 3.  The threshholds for Fat Burn, Cardio and Peak are not appropriate for me.  The Fitbit app allows me to set a "Custom Heart Zone" by going into Settings > Activity & Wellness > Heart Settings > Heart Rate Zones, then checking the box for "Custom Heart Zone".  I'm 70 years old, so I set the Lower Limit for 90 bpm, and the Upper Limit for 105 bpm.  This keeps me in the 60% to 70% of maximum heart rate for my walking exercise.  However, I can't find anywhere on the watch, the app, or the web dashboard that provides any information on whether or not I reached these custom heart zones I set.  It makes no sense that Fitbit would allow us to enter the custom data, but not use that data in any of their screen reports.  Am I missing something?

With the new app, after a workout, one cannot see anymore the custom heat rate minutes.
This was the reason why I bought my Fitbit, and it did not exist anymore.

But it disappeared with the new app? Now,  after a workout, I can't find the custom heart rate minutes anywhere!?
