Which general topic do you have
Referring to Maps: how to use it? - I did not get any answer at all. But the topic still exists - I don’t know, that the Maps application is used for at all.
for some reason you started a Support topic in General category. Unfortunately you ignored the template and a lot of information to help you is missing. Please edit your original post and add all required details like Nextcloud version, webserver type and version, os version, related log file content. Use the support template.
Without additional information the community members cannot help you.
maps works "itself"and shows pictures if they ship geo-location..
