We do not remove mentioned functionality. But I really cannot help you without seeing your code and living example. Sorry.
Maybe https://api.windy.com will help you.

@stitch Sure, there is a picture from my local development IFR branch :-)

@stitch You are right, freezing altitude is wrong. Thank you for your repeated reportings. New fixed version will be available soon.

@saaneuvos You are right, we fixed it a few weeks ago. We are about to update API lib this or next week. Thanks for the report!

@StuartV Sorry for the delay, could you please share the link where it does not work for you? I am not able to reproduce the bug.

@Gkikas-LGPZ It is not so easy. It depends on values around, on geopotential height, on the decrease in value with height and more... But here is a picture with imprinted values. Hope it is what you need :-)

@brauneis Hi, we use OSM data, but we generate our labels/tiles/search indexes/... from time to time. It can be some already fixed bug in OSM.

Hi, I just checked the picker example (https://api4.windy.com/examples/picker/) and it works for me even for mobile devices.
You just have to style the picker for mobiles, Windy API does not care about responsivness, you need to handle it on your own.

@ivo Someone could believe it :-)
