Cookie is damaged and can't be opened every second time it's started
I bought Cookie6 from the App Store. After install and setup, the next time I start it, it doesn't start.
After a while and sometimes right away I get this message: "Cookie is damaged and can't be opened. Delete Cookie and download it again from the app store."
I tried importing cookie 5 settings, not importing them, doing iCloud sync not doing that and in between deleting all app data mentioned here: https://support.sweetpproductions.com/topic/561/full-uninstall-of-cookie-5.
FYI, I uninstalled all data from cookie 6 also to retry.
In short, the second time I start cookie, it crashes. How do I resolve or trouble-shoot this? Cookie 5 worked without flaw ever since it was released.
