I'm Asking This question after trying many times.

I'm using ai2u and aioffline nb183c and 182b
All are offline versions.
Please if you can help me how i can use thise things in my app.

Is this a compiled app ?

Does it work OK with companion ?

What are you doing with firebase once you get data, saving to file ? (could be permissions...)

Please show your relevant blocks.

The App Compiled And Installed On Real mobile But It Closes When I Try To Open. There Is No Error While Compiling.
