I'm still having a difficult time importing. I have the app on my desktop, my phone, and my tablet (loving the app). I've spent time building up some custom tables on my desktop. I wanted to export/import all of those over to my tablet. I used the "Export Oracle Tables" option on my desktop and exported them all as one JSON file.
Then I tried to import that JSON in my tablet app via the "Oracle Tables" option. I figured it would just take in the whole structure and contents of the big JSON file I fed it and would then show all of my tables on my tablet just the same as they were on my desktop. But nothing seems to import or change.
