No arrow or number on watch? – Dexcom Follow Review

I use the program to follow my son who can sleep through any alarm. In the past touching my Apple Watch would bring me his number and arrow along with the graph. Now I only get only the graph. We reset everything and still no arrow which is the best part of the Dexcom system. Not sure if this is my problem or Dexcom’s. If I get the arrow back I’ll return to five stars.
