I was talking in deep in the weed OSM signal group and apparently its a split between the address data not being present, and OrganicMap / CoMap being bugged.
The way to triage is asking nominatim, the geocoder from OSM. If it can resolve : its on the client side, if not, its a data problem.
I'm just parroting here. Happy to learn more.
This is THE only issue I have with those OSM client ( I don't care about traffic )
