Collapsible slow and no animation on Android

I've copied the example in the Example folder.

When opening it on my Android emulator or on my physical Android device, it is 9 of ten times very slow. The 1 out of 10 times it isn't slow, it becomes slow after the first hot-reload.

When pressing a button it takes about 0.5 - 1 seconds before the collapsible responds and opens/closes. I thought it could be because of too little memory on my emulator, but my physical device should be fast enough (Nexus 6P). I thought it could be because the rest of my app uses Redux, but the example obviously doesn't interact with that.

Could it be an Expo issue?

I saw some similar issues on here, but not really a solution.
