to start I have exported the bookmarks.html from my browser at work. The bookmarks are organized in folders in the toolbar menu of firefox. If I import the file, only the bookmarks are imported which are not in a folder, all others are missing.
For test purposes I have copy the other bookmarks from a folder to the other bookmarks tab in firefox, export and import again and these are shown correctly.
Seems that only the latest DL tag in the hmtl file is imported. Are there known problems or solutions?
Sorry for the delay. This sounds like a bug. Which browser did you export the bookmarks from? Firefox I assume. Is there anything in the nextcloud logs?
