Firebase db component not working

@KodularCreator Firebase db component is not working . I am trying it to link a label with firebase from last 2 days trying what not. But it didn’t worked for me. And same blocks in thunkable worked super fine. I want to update one label in my app every week using firebase. please help me . I want to build my app on Makeroid because of its admob rewarded video feature which thunkable doesn’t have yet. Please help regarding this.

One more suggestion , I can’t use Makeroid Companion without WiFi . I want to use it with my mobile internet. Please look into this matter also.
