Yeah - the react-native-localize API move was the biggest thing but I coordinated with the maintainer there to make sure every API existed with the same semantics. It’s a great package and should serve us all well. Cheers

@mikehardy I totally agree with you, seems like hermes needs more time to be used without any or with a minimum of problem.

@ethanneff @mikehardy Yeah, the API changed all to promises since 3.0.0 and some API was removed like getDeviceLocation that was the one that was causing my problem. Well, I just add the react-native-localize package for that and solve my problem for now.

Thanks a lot for the answers!
