Hey @Dexwell , were you able to reproduce this in the playground app?

[Dexwell]

I can't get the Playground app to build—is there a guide to this?

same here :/

I found one way to reproduce it:

1. Show modal
2. Show another modal
   Second modal isn't animated 🤷‍♂

I'm having the same issue.

[3luyka]

I've replaced

Navigation.showModal({
  component: {
    name: 'example.Screen'
  }
});

with

Navigation.showModal({
  stack: {
    children: [
      {
        component: {
          name: 'example.Screen',
        },
      },
    ],
  },
});

and animation works as expected. (might be helpful)

Can confirm @3luyka's solution works; would be great if both ways worked and not every showModal call will have to be updated though.
