Watch and Garmin connect not showing heat acclimation

I know this doesn't help your issue, but I was just in NY and DC where I ran in >28C each time (unavoidable) and got the heat acclimation (still at 42%). Not sure why it hasn't registered for you. Good luck.

Looks like the 'problem' is the weather widget, currently in Levico therme in Italy, about 30-35 degrees. When the user settings in Garmin connect app on my phone is set to location data from phone Garmin picks the weather station in Paganella, maybe it's a high elevated point but the temperature is 15degrees there.... Unfortunately I am unable to set the location manually, when I do that there is a red examination mark is showing on the weather widget of the Watch. My Garmin 530 has the same issues.

This is a picture of the weather widget, it is above 31 degrees at the moment.

Have you looked in the. Training  status glance , my heat acclimatization is one of the sub screens in that glance  

Yes I did I had seen it there but now it's missing for some reason, missing on the training status glance and also missing in connect app

Never seen it on the connect app myself. At one stage it automatically added to the bottom of the glances on  my watch then somehow it nested itself into the training status glance . All quite odd 

This is my training status
