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.

Welcome Venus

@venus AI2U best way to get help with its software is by visiting https://groups.google.com/forum/#!forum/ai2u. You are probably dealing with a AI2U issue since your app works with a MIT App Inventor2 built apk. MIT does not support AI2U.

Thanks Steve for the prompt reply. I shall verify in AI2U forum.
