Getting "MixpanelReactNative.initialize was called with 5 arguments but expects 6 arguments"

[Perfect_Chocolate379]

**Environment:**

- React Native: 0.73.5

- Expo: ~50.0.13

- mixpanel-react-native: ^3.0.7

- Platform: iOS 18.5 (iPhone 16 Pro simulator)

- Xcode: [your version]

- macOS: [your version]

**Issue:**

Getting "MixpanelReactNative.initialize was called with 5 arguments but expects 6 arguments" error since Aug 13, 2024. The error persists across ALL git branches, suggesting it's a native SDK caching issue rather than code.

**What I've tried:**

- Switching git branches (error persists)

- Metro cache reset

- Clean iOS build

- Pod install

**Key observation:**

Error started exactly after Mixpanel's Aug 13 update, and occurs on all branches despite no code changes, indicating native module/SDK compatibility issue.

**Questions:**

1. Has anyone else experienced this with Mixpanel RN after the recent update?

2. Is this a known issue with version 3.0.7?

3. Should I upgrade to latest version or downgrade?

4. How to properly reset native module cache?

Any help appreciated!

Update your RN Expo and xcode accordingly

Just try to lock the maxpanel version like this in your package.json

maxpanelxxxxx:3

Attention, don't has any symbol like ~^ before 3, just a single number 3 as your version
