@rlsmith01773 I was having the same issue and I found a post in another thread made by SimonUrbanek that fixed it for me. I’ll post it below. It was made for android in mind so when it says to refresh the widget you will have to remove it and put it back because IOS is awesome like that.
“Hi everybody,
I am trying to induce this problem, but the units in the widgets are displayed correctly. I think the error may occur in the synchronization between the application and the widgets. Could you please try the following: In the application in the settings, switch the units to for example celsius, then refresh the widget and then again to faranhait and refresh the widget again? When you change the units in the settings, the settings in the widgets will be synchronized. It is possible that the data for the widgets has been lost and this is how it will be uploaded again. Anyway, I will check the synchronization mechanism again.”
