This applies to all my systems which are running Windows 10x64 Pro Version 20H2 (OS Build19042.867) and my test system running the latest Insider Build 21332. All have WWL v7.45 installed. My weather station is for 25177 and is SAINT ALBANS, WV (Near Lakewood Elementary School).
Since daylight savings time ended, WWL cannot display the temperature in the tray icon. The tray icon consistently shows NA. As shown in the attached pic, data appears to be downloaded but the tray icon continues to show NA. The weather map updates okay. I have tried switching weather stations but with no success. I completely uninstalled WWL and re-installed, but the problem persists.
