Hi there, i already created an issue on Github several months ago but it is not there anymore?
Is this why there was never any response? There should at least two issues from me.
However, often users reported a broken upload feature in the Advanced Editor.
In this case, there is just a link to markdownify an image without an upload option.
In the case of the issue i was able to reproduce this on webkit based browsers but not in Firefox.
Ironically also a Firefox user reported this to me.
