I am trying the Show the Local Weather challenge and decided to check what the API returns, so I opened a new tab in Firefox and entered https://weather-proxy.freecodecamp.rocks/api/current?lat=51.6565489&lon=-0.2008189
I initially get the correct information (relating to High Barnet in GB) but if I refresh I get information relating to Shuzenji in JP and I cannot seem to get the correct information again.
Note that the Shuzenji data shows lat as 35 and lon as 139:
Why do you think wrong data is going to stop you from making a working app?
You need to use the location of whoever open the app anyway, so you are working with dinamic data.
Anyway now the data from https://weather-proxy.freecodecamp.rocks/api/current?lat=51.6565489&lon=-0.2008189 is again High Barnet, so there is probably a cool down or something on the API
