I think I’ve figured it out. Whichever screen is first when you open the live app loses functionality. ---

Hi @wakangariolanaig Thanks for sharing more information. It seems that the issue is happening only on the first screen of the Bottom Tab Navigator, and if the navigator is removed, the blocks work. Thank you, again, for your time and patience in this matter. ---

Hi @kizzy Could you please share the specific project URL with us so we can investigate it further? ![](https://downloads.intercomcdn.com/i/o/759644115/d4a89684a0bda74ab75c59e6/Screenshot+2023-06-08+at+4.13.55+PM.png) You could copy it from the top of your browser. This way we could find the best solution for you. ---

Hi @wakangariolanaig The issue is happening because the app variable is initialized with a function block: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/c/ac07f6f06df7f33562766b645edb02c914da1241.png) Could you please initialize the variable with a text block and delete the function? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/6/c6a903652bc97099b729fadea8e13e5d4e1f9b7b.png)
