Someone PLEASE help!! Its driving me insane now. I want it to show in miles but it just wont change. I have an account on my iPhone app which I’ve logged this account into my PC. On my phone its in miles but on PC its in KM… I’ve tried clicking on account settings and yep it says change from metric to imperial and vice versa but when I go back to the plan a route map its STILL IN KM!!! So frustrating and cant believe its this hard 
Are you referring to the live map here: https://www.waze.com/en-GB/live-map/ ?
Unfortunately, it always shows in KM, not matter what you have set in https://www.waze.com/account it’s a known issue that Waze isn’t giving any priority to fix.
I am indeed - that’s so annoying !!! Thanks for replying though appreciate it. Come on Waze sort it out!!!
