Hello, I have had a similar problem. I'm not in Airplane mode I'm just off line as I don't allow data roaming on my phone. I just create a new file without even naming it and then I periodically get very annoying dialog boxes that my phone cannot connect to dropbox. These boxes come up while I am typing interrupting the flow of my typing. On my commute this happened today and when I got to my desk with wifi the app started to connect and then all of a sudden my untitled.md document disappeared and I was presented with a blank screen.
Luckily I found the above post and was able to recover the document. I however lost work previously in Editorial 1.1 and didn't get it back so I use Editorial much less these days due to my loss of trust in it. I was eagerly awaiting and hoping that the 1.2 version had fixed this problem.
