I put import 'react-native-get-random-values' before import Realm and the warning stopped.

import 'react-native-get-random-values'
import Realm from 'realm'

@xtianmpimbaza, nope, still haven’t found a way around it. In my case, it doesn’t prevent Realm writes though.

@kneth, any idea why those warnings are showing?
