Problems with the Update - Neo Monsters - ZigZaGame Forum (neomonstersforum.com)
We have just released an android update that should be fixing various issues to do with region/language settings. It should also fix the issues with screens sometimes freezing.
If you are having these issues please update (It may take up to a couple hours to appear on your Google Play store)
The same update is coming for iOS and will be released once Apple approves it.
If you have updated to 2.24.2 and still experience this issue, please leave your information here again.
