Resubmit it and put a note to tester saying
Note: Weather API location is the Weather Station location not the mobile location.
In the case of the Korea test site this happens to be a transportation terminal
If they reject it again create a support request with Samsung Developer Program and ask that I be copied. I’ll need the rejection letter too.
Don’t use the tap to change weather unit. That is very flakey and erratic and will cause rejection.
