1.20 for iOS is finished and back in review at Apple:
I have fixed all the violations, integrated new Dropbox SDK, tested it, scanned and rescanned for anything that might upset Apple folks. Hopefully, this time it will go better with them.
I am now back at work to finish 1.21. All the major things are done. What’s left are some details and testing. Likely, I’ll have that wrapped up before Apple make up their mind on 1.20.
