For the last 2 weeks my weather app on my Versa is constantly switching between Fahrenheit and Celsius. Each time I check the settings and it's always set at Fahrenheit no matter what my Versa itself shows. For the last two days I have been stuck on Celsius on the Versa but the settings are still set for Fahrenheit. I've had days where it is constantly flipped between the two different types of readings. Help!
