I removed all your spacers and the kitchensink component. But that was not enough.
You have a lot of images in your app that are much to big. You should try smaller ones.
You have also used other blocks like decoration and a lot of screens and a lot of blocks in every screen.
This is a hard one. I didn’t yet succeed to import it. And i don’t know if i will succeed.
