Redux-Persist not working on React-native#0.60.4 - react-native

Question

I have been using redux-persist for about 6 months, it never happened but this time in my new project redux-persist is not working I don't know what's the reason. Please note that I cannot downgrade as I'll have to re-eject the project and I can't do that. Need a quick fix.
Any help will be appreciated. Thanks.

I was able to resolve this issue by adding "persist/REHYDRATE" action in my reduces, However I have no idea what this action does but resolved my issue
case "persist/REHYDRATE":{
return{
...action.payload.global
}
}
Where global is the name of my reduces
