Just tried to update Accordance on my iPhone 4S to iOS v. 1.6.6, and after 2 tries I am still unsuccessful. The first time it hung installing the update, and after deleting the app, restarting the phone and attempting a fresh install through iTunes it is still hung half-way through showing an "installing ..." that never finishes.
Installing the 1.6.6 update went through just fine on our other iOS devices (iPad 2 and iPad Mini), though as others have reported here it wiped out our account logins for the Dropbox link and our Accordance account.
So at this point I'm dead in the water: no more Accordance on the iPhone. Any suggestions on anything more I can do?
