Is this your problem? > [@Events Not Working](https://community.thunkable.com/t/button-not-pressing/1495834/4): > > I think the problem is caused by a block, but I’m still testing to find out who. Because I have projects that load without a problem. PS: I only have this problem on Android devices ---

It sounds like your blocks are wrong. But you’ve provided very little information about what is happening with your project. Screenshots are helpful as are more details about this situation. ---

This is not the URL of your project as @tatiang suggested. This is rather a video to show your app is crashing. ---
