Insecure – iSpreadsheet™ Review

I bought this app, storing my sheets on my iPad. The latest Apple OS update now results when I try to open the app in a message saying the creator must update the app. They’ve tried but none of those changes have allowed me to recover my data. I even bought the Office version. It didn’t help. I’ve written their support, but now they only respond with an automated message. I would have thought they owed paying customers more.
