Heat Acclimation does not work on my Edge 1050

I live in the desert and at the end of my rides, the temps are > 100F.  However, the heat acclimation widget says "Train at 72F or hotter to see how you are acclimating".   I have location services for Connect set to always.  Any other ideas about how I can get this to work?  When I had my 1040, it worked great.

TIA, Dave
