Update still has the flash of the new skin, and sadly the backup to iCloud does not work. It generates an error message "invalid arguments. Server message= cannot create a new type in production schema" ! Works great on an iPhone 6. I do regret though that having chosen the “old” calculator skin, it insists on showing briefly the new skin before switching to the “old” skin… That brief flash of a different color is disconcerting …. Please change in a quick update soon !
