hi it was with great enthusiasm that I turned to Thunkable. The blocks used for android do not work directly for ios you have to adapt In my application I use firebase ![Capture d’écran 2022-01-16 à 14.04.47](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/f/3/f39bc89f4ca285f491b8707c4371d0b94df526ad.png) this block in android reads my data and not in ios (I get an error code undefined) I have a great need of your lights ---

To answer the question in the title: The meaning of Cross Platform is that you develop one app and it should theoretically work for Android and iOS. However, I don’t know the solution to your particular problem, perhaps someone who knows can help. ---

Ive not run into many issues in 2.5 years between platforms for these blocks specifically. That said, it doesn’t mean something didn’t get messed up on our end by chance. Any chance you can create a minimal example that demonstrates this behavior. We’re not getting any other reports yet but I’d be happy to check things out. ---
