Thanks agsteele. Unfortunately I can't submit a support ticket because that is not available for free users, and I was going to become a paid user (again) if I could get my notes imported into Evernote but it looks like that is not possible so I'll just have to keep looking. I did find some possibilities which I'll post here in case others have the same question. I just found them and I'm about to start looking into them more. In case it is of help to others with the same question, here are the possibilities that I have found so far that may do the trick for importing HTML format notes, and that overall look like good platforms:
Notejoy dot com I have not tried yet but looks very promising
Notesnook dot com I have not tried yet but looks very promising
Microsoft OneNote - look at the 'getonetastic dot com' add-on I tried it a little bit, seems OK but overall I have issues with Microsoft's quirks and bugs
Notion dot com I have not used this one yet for importing, but I tried it last year for tasks & notes and I found it to be overkill for a single user, seems geared to large teams
“Notebooks” notebooksapp dot com Did some basic testing, it is like a notes app, document creator, file manager all in one. Powerful and very impressive. If you need something for just basic notes this would be too much, but for an option with a plethora of features and editing capabilities it could be the most advanced I've seen.
Thanks to everyone who replied and all the best to everyone who is looking for HTML notes import options.
