The building is there but no address is assosciated with the outline. Can I contribute my address to OSM?
OSM requires attribution (https://osmfoundation.org/wiki/Licence/Attribution_Guideline...), and I’ve never seen OSM attributed on their site (it does show third-party data providers sometimes, depending on zoom level and what part of the world you’re looking at, so it may do so for some parts, but the higher zoom levels seem to use only Google data)
Also: chances are your address already is in OSM, as you say it does show on Apple Maps, and Apple does use OSM data.
