@DTLow just tried to export as an *.enex and as a *.html, just as you suggested.
Neither format was capable to export/show the attachments (simple *.png, *.jpg, and *.pdfs attached to the original notes)
But, when I open the note, using the legacy version of the app, everything works.
Using the new version (just made a fresh install, to be sure) still shows only the text part fo the note, no attachments 😞
Maybe I would have to export everything as an *.enex file from the legacy version, and import again to the new one.
Is sad to know that Evernote is not reliable anymore.
Imagine if you need a old note, some years from now, but legacy is discontinued in that time in the future,
so the info you trusted would be there, no longer is accessible.
The whole purpose of the app is lost.
No notebook encryption.
No local folders.
And now, not even a reliable solution for filling/storing.
Evernote seems to be kind of sinking.
Thanks, for the help anyway.
