Just noticed that this is still happening (and it's happening right now since we are at the end of month again...).
Looking at the code, it seems that the issue comes directly from the server side. The server returns a ux: null in the trend array after metar which is why all the wrong time have exactly the same value, howOld treated it as 0... The returned time is in fact the time since Unix epoch....
@David-PIssouri Hi, please follow the steps in this article - https://community.windy.com/topic/11832/what-to-do-if-you-can-t-access-your-windy-premium-features
You need to restore your Premium on the device you made the purchase on.
@Korina Yes, but that requires extra knowledge (via each user asking on e.g., this board), as there is a disconnection in the path the user needs to follow from the first red "1" to the next click he needs to make to see what the red "1" is all about. That is because the second red "1" is missing from the four line menu.
