On: Streets GL – 3D OpenStreetMap

You could add a building:levels value to the object in OpenStreetMap, to record the information of how many stories your building has.

While a good idea in general (the StreetComplete app makes this very easy, by the way), this won't help for this app, as the data is from September 2023. Otherwise I'd love to use it more to validate how renderers handle different buildings. F4Map should show the change fairly quickly, though.
