Instinct 2x solar tactical : inaccurate weather data

Hi all,

weather widget on my 2X Tactical always shows inaccurate data. For an actual temp of 36C, it shows 21C for most or the time. From time to time ( no way 20-30 mins, it takes hours to update), the temperature reading on the watch gets updated, still not correct.

Synced and connected with phone, gps and phone settings ok, no luck at all... :( Any ideas???
