After update Redmi Note 6 Pro to Xiaomi.EU Stable 11.0.5, calculator and weather apps doesn't work.
Calculator - crashing, not open
Weather - when you click, just open a white screen
When i set the system language to English, the calculator app works !!
I returned the system language to Portuguese, and the problem with the calculator was fixed !!
I have the same issue. The weather app is capable of retrieving weather info (it shows on notification shade) nut when opened it shows a "blank" screen. Clicking on a city crashes the app.
