Hello @david-ck, I can recommend clearing app's/browsers cache.

@wxgeek This is available, here with wind layer and isolines at 500hPa level, but they can overlay most maps. Adjust level and select More layers > Geopotential isolines Only Wind, Temperature, Humidity, Dew point are shown at this level, the other like Rain, Clouds, Pressure, Waves... are not modified, of course, by the altitude slider but can be overlaid by 500hPa isolines. With customized colors
