Change from Celsius to Fahrenheit

I live in US and when ST was set up recently it put it on Celsius. I’m directed to change location but it’s not changing. Says geolocation temporarily unavailable.
It’s been this way for awhile.any suggestions?

In the ST app…
On the Favorite screen… You can click on the Home icon in the upper left and select Manage Locations or click on the 3 dots in the upper right and select Manage Home. Then click on the address field.

Is that where you receive the error message? If yes, contact ST support to investigate. Click on Menu and select Contact us to find the methods to contact support.
