QA IN PROGRESS

thoughts so far

To address the issue of components not updating when profile picture changes occur, consider using a timestamp field in your Firestore document.
When the user updates their profile picture, also update the timestamp field.
In your context listener, compare the timestamp with the existing data to determine if an update is needed. If the timestamp has changed, trigger a re-render of the affected components.

Firestore automatically caches data locally, so you don't need to worry about unnecessary refetching.
However, if you encounter issues with stale data (e.g., cached data not reflecting recent changes), consider the following optimizations:
- Cache Control: Use Firestore's cache control options to manage the cache size and behavior. For example:
```
// Initialize Firestore with cache size control
const firestore = firebase.firestore();
firestore.settings({
 cacheSizeBytes: firebase.firestore.CACHE_SIZE_UNLIMITED, // Adjust as needed
});
```
- Timestamps and Synchronization: When updating data, ensure that the timestamp field is updated. Firestore will automatically synchronize data across tabs and devices.
- Manual Refresh: If necessary, provide a manual refresh option in your UI (e.g., a button) to force a re-fetch of user data.

components will stay up-to-date with the user's data, even when specific changes occur.
handle error cases gracefully (e.g., user not logged in, profile picture not available).
