Missing addresses and places

For context I switched to Magic Earth a while back as it was the best Google Maps alternative to me, however with the recent switch to a Freemium model that also introduced a ton of bugs, I'm looking for other alternatives.

One thing I noticed immediately about comaps is its misssing a LOT of addresses and places here in the US that were available on Magic Earth. Can I somehow manually import better address/maps data? It's to the point it's really not usable for me but I'm struggling to find anything else that works nearly as good as Magic Earth.
