Do you remember what you've used to add your business? The process shouldn't be so difficult and normally the changes to the OpenStreetMaps database are instant and don't require any moderation or review. There are some sites that were intended to help business owners to get info to the database, maybe there's a problem with one of them.

> The actual business is listed, but with a slightly wrong name. But I can put that exact slightly wrong name into the search on openstreetmap.org right now and there's zero results.

Can you give the name and location? I can look it up to see if there are any errors.

> Then I can manually zoom to the location (which is correct), see my business, tap on it... And nothing. It doesn't open. So given all of this, why would I bother with openstreetmaps as a business owner?

That's the part that annoys me the most. Counterintuitively the map at openstreetmap.org is NOT intended to be an interactive common user web-map, a Google map alternative. It is a non-interactive map for the mapping volunteers to get feedback on whether their changes to the OpenStreetMap database were correct. While you can still right click on a feature, select "Query feature" and look at the raw text, you are better look up your business on something like mapy.com or an app like CoMaps (that use OSM data to create a Google map alternative) to understand what would the users see.
