Unable to answer "What’s the house number of this building?" for https://osm.org/way/347541575 via StreetComplete 45.2:

This isn't 400-402, it's 400 and 402, two joined buildings; maybe that should be drawn as one, as it is, but in that case most of this street should be drawn as one huge building.
