Localization Failure: Temperature Is Hard
A bit related, but I hate how many errors I get because I want my system language to be English instead of my native language (Norwegian) on my laptop, phone etc. Because I don't want a badly translated experience. However, I still want units in meters, Celsius, dates written sensibly, time in 24h format etc. But not all apps understand this, which is quite annoying. It's like they only look at the language and make a decision, even though on OS level there's more fine grained locale settings.
