I’ve discovered a problem in the premium version of Klikaklu, that can be pretty crippling to the app. It will likely manifest as clue images always being rejected as not containing enough information for matching.
A fix is pending, but will take some time to clear through the app store.
If you purchased the premium version, you can, for now, delete it and install the free version. That will allow you to play hunts indefinitely and create them for a week. If this takes longer than a week, and your trial expires, contact me, and I will see what I can do to help you out.
Very sorry about this, hope it isn’t causing anyone too much pain.
