I have also discussed this issue with people from the Balearic Government / official cartographic institutions, because the problem affects official geographic information. However, even they have not been able to find a clear and effective communication channel with Apple Maps to resolve these data issues.
This reporting function does not seem to work properly for different types of map data. It fails not only for official city and town names, but also for neighbourhoods, duplicated or non-existent areas, and POIs. Even when the correction is supported by official geographic sources or clear local evidence, the reports are rejected without a useful explanation or a real review process.
