One temporal solution/workaround I would like to see: Hero Lab could implement the "Open in" dialog, which in turn would allow to save profiles to the Dropbox (or other) app to save it to the cloud.
It's a bit cumbersome, but it is doable using HL as-is.
I opened the DB app and selected the portfolio file. DB told me it couldn't display that file type (and the Help link pointed to an outdated article; oh well).
I tapped on the three dots in the upper right and selected Export. HL did NOT show up in the list of apps, nor was it in the extended list that simply needed to be "turned on" so it would display. I'm guessing that HL doesnt register itself as being able to handle files with the .por extension and/or doesn't register a MIME type with iOS and then declare itself able to handle that MIME type.
On the second row, however, towards the end of the list, was "Open In..." I selected that and then picked HL from the list and the portfolio was imported into HL as a "local" portfolio (meaning it appeared at the top of the screen).
So Open In does appear to work using existing techniques, it's just very cumbersome to use. Note that getting the file out of HL and back to DB will involve mailing it to yourself, then opening the email and tapping on the attachment, choosing to store it in DB. And you'll need to navigate to the DB folder where you want it stored. (I may look into creating a top-level folder in DB for HL stuff so that the navigation part is a little more streamlined, but there doesn't seem to be any other solution.)
Until LW corrects this problem, I may configure a new email address with an auto responder that just extracts attachments and moves them into a particular folder on DB. Then I could email them to "hl@some.addr" and they would just magically appear in the correct DB folder with no work on my part. I might be able to use Automator on my MBP to do this, but most likely I'll end up writing a Perl script to do it and then run the Perl script as a rule in my mail client. (That's not perfect, because if my laptop is sleeping the file won't get processed, but at least it's automated.)
Will the new file explorer in iOS 11 allow to access HL files and move them to a cloud folder?
I don't have a beta of iOS 11 to test with, but I'm thinking that dropping a file should produce the equivalent of Open In. That would be easy to implement, both for Apple and the app developer, so it's the path of least resistance. If true, then the iOS 11 Files app should be able to get portfolios into HL even easier than I described above, but getting the data back out of HL is still going to be a PITA.
