@itsramiel If you are using the RN SDK v3, you can just set eg persistence to memory or set your custom customStorage when in testing mode, for example, you can check the __DEV__ or something else and set those properties during the RN SDK init. https://posthog.com/docs/libraries/react-native#configuration-options

Does that help?

@itsramiel did you try this out?

@itsramiel did you try this out?

Oops forgot to reply. Yes that was my workaround anyway since it was already mentioned in the previous issue, but I thought it was a regression since it was handled internally after the creation of that issue.

If that's the solution going forward, then alright

Gotcha, yes that is the workaround until those libraries provide the implementation of the missing platforms.
