I bitterly regret updating my iPad to iOS 11 as now I can’t access my iNotes app, when I click on it, it says to contact the developer as it needs updating but I have no way of doing this as it’s no longer in the AppStore and I can’t get into the app to find out who the developer is. I have a ton of important information stored in iNotes that I’m totally lost without but googling failed to find an answer to this problem. Please can anyone help?
