If any of you have the problem with Bing weather, especially with inaccuracy, try this:
1. Uninstall the app and restart the phone
2. If you live in, for example Italy, make sure that your region, language, reg. format is set to Italy. Also check your Microsoft account, check region, time zone etc. Restart the phone again.
3. Install Bing weather, choose your city, and it should works.
I don't know how, but it works for me. This app was very inaccurate, shows for example 15 Celsius and cloudy, and other apps show 20 Celsius clear(the weather was clear outside). Now it's accurate, live tile works great, no problem, testing it last 3 days...
