If we're sharing problems contributing to google maps: I tried submitting a correction to google maps for the first time a few months back. A cafe was listed in the wrong location by about 100m. Very confusingly putting it on the other side of the station it's in front of in a different building.

I submitted the correct location and it said the change required manual review. Then a few days later I got an email that the change has been accepted. But opening google maps it was still in the same wrong location, and it's still wrong now.
