Can't retrieve data stored from extension in main app

[mbenassarou]

Hello,
I am using MaxAst/Expo-Share-Extension and when I store data from the extension and open the host app from the extension, the field remains undefined, unless I close the app and open it again. It looks like the data is not up to date when I switch directly from the extension to the app. Is there a way to 'reload' the storage when going back to the main app from the extension ?
Thank you

Do you use AppGroup?

Hi @mrousavy ,
facing data loss in iOS only.
I’m in a bit of trouble after moving from v2 to v3. My app is already live and users are reporting that their local MMKV data is gone.

Setup:

I use export const storage = new MMKV(); for local app data.

I also have an AppGroup key in Info.plist, but group-shared data is managed separately with react-native-shared-group-preferences (not MMKV).

After the v3 upgrade, MMKV seems to auto-detect the AppGroup and now points to the AppGroup container, which makes the local store look empty.

Is there a way in v3 to exclude the AppGroup auto-detection so that new MMKV() only uses the sandbox path (like in v2)?

Thanks a lot 🙏
