.......and now for the sad news. Once again the dev emailed me and stated that while the update has been sorted out, the issue with their developer account still remains and the game will only be available for purchase for a day or two. It will then disappear from the AppStore forever. They said that so long as someone has purchased the game it will always be available for download but I wonder if they realise they have to pay Apple to keep it available? At least the Steam version is there.
