Hi @diamondex
According to the Expo SDK 46 release announcement, the latest version of the Expo Go app is in review:
Note: Expo Go for Android with support for SDK 46 is not yet live on the Google Play Store — it is currently in review and expected to be released soon. You can install the latest Expo Go by downloading the APK directly or connecting your device to your computer and letting Expo CLI install it when you launch your project.
I suspect that is why you’re getting that error.
You could also try switching the snack to SDK 45 at the bottom right of the snack editor.
