I just updated to version 29.2.4 and the widget shows Prague as my location rather than my actual location. I tried deleting data, reinstalling, and logging out/in to no avail.
This is with an iPhone 11 Pro running iOS 14.5. Location is disabled for the Windy app as I prefer to set a permanent location for weather info.
Thank you for looking into this. I use the widget multiple times daily and hope there is an easy fix.
