Since upgrading to iOS 8 I can access all my information apart from data I've encrypted with the master password. Whenever I enter the master password it tells me it's incorrect. I know for a fact it is not incorrect. Any ideas?
It sounds to me like you might still be using 1Password 3 for iOS, but just to confirm, I'd love to get a little bit more information about your 1Password ecosystem:
The more detail you can provide, the more quickly we'll be able to get you sorted out!
