Black badge MPG and yellow MPG not the same- no partial fill-ups.
My MPG shown within my badge in the dashboard section vary from the MPG shown in yellow then I click on my vehicle. Dashboard MPG is 2 UK MPG better / higher Why is that? No Partial fill-ups.
It appears some badges take longer to update than others. In the screenshot you can see that the badge on the lower right is 118. A short time later, maybe 45 minutes or so, it updated. It just wasn't instant like you think it would be. Was that your issue Nicolai?
Badges are invalidated every time something is changed that is going to generate a new MPG. If you see the old value then you are seeing it being cached by the browser. If you open the badge directly in your browser and CTRL-F5, you will see the new value.
