Hello Everyone,

I have created a simple app in [https://x.thunkable.com/projects/5ddeadca057823c6c2ee4f19](https://x.thunkable.com/projects/5ddeadca057823c6c2ee4f19)  
and while it works great on the preview, after compiling, downloading and installing it on Android it throws the following error.  
Any help on what this means would be great!  
Thank you

Looks like an issue with one of your Json animations.

Try removing the animation first to see if that helps.

I’m glad that worked for you but it’s a bummer your animation didn’t work. Have you tried to test an alternative.
