When I preview my app, tells me to check my blocks, although I have none, and even when I downloaded the app, it still didn’t work. It stopped working very suddenly. I used the drag and drop builder.

Hey @1times94is942fjkz!  
I could try to help you if you could send a screenshot a link to the project. Maybe there are some components wich android doesn’t support. [Here is the list of unsupported components in Preview](https://docs.thunkable.com/publish-as-a-web-app-pro#unsupported-components)

I figured it out. It was the banner ad, and I didn’t have premium. Even though I removed it.
