I inserted various footnotes into my notes. When switching into View Mode, footnotes from 1-42 work properly, however, from footnote 43, it is broken (as per attached screenshot)
It will be useful if you provide specific steps and in this case for example a sample note so that other users can see whether they can reproduce your issue or not. Also, make sure the source code is correct - we currently cannot know if that might be the cause of the problem you see.
Hovering at the footnote inside the 1st heading, I can view the footnote’s content
While hovering at the backlink inside the 2nd heading, which links to content of the 1st heading and containing the above footnote. I cannot view the footnote’s content (As you can see in the last screenshot, the footnote displays as a normal number instead of a backlink)
That is clear. While clicking other links in a pop-up will replace the current note with that popup with the destination, following a footnote from within a pop-pop does not work. This is a current limitation in the software and has to be implemented by the developpers. So probably the only action you can do is file this as an issue, if it has not yet been filed. Then this may work as you expect in a future version.
The current workaround will be to Ctrl+Click the link to open the note in a new tab instead of in a popup, from where you can continue to the footnote.
