Hi @Kelly-Drewry , thanks for your report with screenshots.
Can you please tell me what "location icon" do you actually mean? Is it the "arrow" (Find my location), or the "house" (Start-up location) ? Thank you.
In any case, this topic has been discussed and regularly updated here: https://community.windy.com/topic/6813/start-up-location-vs-find-my-location
The same for Android 7.0 (Samsung Galaxy J3 2017) : Windy app, Chrome, Firefox (and Samsung Internet).
Note: When I click on a different Forecast model, the bar slider moves a little bit, but the value of the altitude stays the same.
Note 2: On Android - the Windy app & all browsers do remember the set-up altitude for 'Wind, Temperature, Dew Point and Humidity' (and also those other layers for which it should not remember & show).
