I imported the same enex file, this time as HTML. Also opened the console as you recommended. Only 8 notes missing this time (instead of 13 as markdown):
Evernote .enex 22331
Joplin imported 22323
Notes missing 8
Providing Dropbox links to two log files:
/Users/jbh/.config/joplin-desktop/log.txt duplicated as "Joplin log.txt”
https://www.dropbox.com/s/q2ihhiifrdvq0wz/Joplin%20log.txt?dl=0
"Joplin Console Log (filtered 8 Errors & 19 Warnings).docx”
https://www.dropbox.com/s/cls0whz4oul78na/Joplin%20Console%20Log%20%28filtered%208%20Errors%20%26%2019%20Warnings%29.docx?dl=0
Unfortunatley, I am unable to glean any understanding from the log files. I wish I understood more about this type of stuff; but alas I am an old accountant. Perhaps you can review the log files to determine what prevented the 8 notes from importing. I assume the 8 Errors indicated are the subject 8 missing notes.
As an aside, as I have read in the forums, the import as HTML produced unusable gibberish (to me anyway) in the note editor column. Once I determine why and which missing notes are not importing, I will import again as markdown.
Thank you so very much for anything you do to help!
