I have purchased a key for Apricus MC OWM Z and the key doesn't seem to work. It states "invalid key" on the weather part of the dislay. Does that meam the watch face key is incorrect or the openweather key is incorrect?

Good Day I purchased the Ochila MC watch face; however was not able the retrive the CODE before the app closed

Code on Watch 6978125947
