Hey Chung_Xa,
thanks for your feedback!
The metadata and bots data are not embedded within the app but loaded at first run (then updated when a new version is available).
The app can run offline but needs one first (initialization) connection to the Chess-box server.
In your case, seems that that those data have not been properly loaded on first run (internet connection down, Chess-box server blocked…);
the app is obviously not supposed to be running without bots data but it seems that I forgot a corner case…
I’ll cover that case in the next alpha release. In the meantime, you can delete the app-data (or delete the full app…), then restart Chess-box.
I suggest to send any further feedbacks/requests directly to me, I don’t want to spoil that showcases thread which is definitely not an app support thread.
