SDK reinitialization with different config

[gtyanchev]

SDK version:

    "react-native": "0.76.7",
    "expo": "^52.0.37",
    "customerio-expo-plugin": "^2.0.2",
    "customerio-reactnative": "4.2.4",

Describe the issue
I have an app that operates in two major regions that have separate workspaces and credentials.
I want to be able to reinitialise the SDK with the correct keys when the region is changed within the app.

It seems like this is not possible at the moment?
Calling CustomerIO.initialize(config) multiple times results in a console warning and the SDK instance keeps using the original config.

Reloading the app using Expo's .reloadAsync on region change and then initialising the SDK, causes the SDK to fully stop working. I think .reloadAsync reloads only the JS bundle, but there is probably some state preserved in the native modules which causes the issue.

1. Is that expected behaviour and what would you suggest to fix the issue?
2. How hard would it be to reset the native module state?

Thank you!

Thanks for reaching out and sharing the feedback @gtyanchev. Unfortunately, there's no way to reset native module instances directly unless the app is relaunched. The expected behavior today is to have only one instance per session. Because if the SDK isn't initialized properly in JS, multiple instances can be created otherwise which may cause unexpected behavior.

That said, I completely understand your use case and see how reinitializing could be important in your flow. At the moment, the only workaround is to relaunch the app to ensure the correct config values are picked up.

Thanks again for highlighting this. It really helps us understand the need and prioritize accordingly. I've upvoted the internal request on your behalf and will keep this issue updated with any progress we make.

Please feel free to reach out if you have any more questions. Have a great day!
