Hi, the app freezes upon launching or doesn’t go past the first screen. I can’t find the error, could someone help me, please? Thanks in advance! [Thunkable](https://x.thunkable.com/copy/4015e3be9bf951aef97d343a728801bb) ---

Hmm, it worked before without the 0… Has it worked for you with the 0’s? ---
