Technical Details

In this iteration, we should migrate async-storage-wrapper.js to access MMKV instead of AsyncStorage since it doesn't have the limitations that AsyncStorage has. To do so, we should leverage getItem, setItem, and removeItem from the wrapper class to perform this migration. In each method.

• getItem -> Attempt to access key in MMKV. Then fallback to getting key via AsyncStorage. Set item in MMKV if we're able to get the key successfully from AsyncStorage.
• setItem -> Replace storage with MMKV
• removeItem -> Also remove item from MMKV

Acceptance Criteria

• App should function as it did before
• New installs should not be interacting with MMKV instead of AsyncStorage

Testing on Android emulator (issue doesn't occur on iOS, and I was not able to test on physical Android device) did not show any critical degradation of functionality after this error has occurred.

Cal and I have done some digging and since the AsyncStorage.setItem() method will error out once it hits the limit on Android, that means that it essentially destroys the app's ability to storage values in AsyncStorage. When this occurs, the app won't even get past the splash screen (doesn't even get to onboarding, see video). Our conclusion is that this shines on a larger issue, that our app needs to be able to still function when AsyncStorage fails, even if it functions in a degraded state.
