Help on downloading app

Hey There! Me and my friends are testing our app, however the program is not allowing us to live test our app. It keep saying that we need to login into the thunkable app, however we already have one. Can you help us so that we can test our app? Here is our design for your information: https://x.thunkable.com/projects/5b3674072f0e3b0b9de1edda/Screen1/blocks

Are you testing on Android or iOS?
