Thanks for sharing what you’ve tried so far with the Notee app on your iPhone. Just so I’m clear, are you seeing any specific error messages when you try to open the app, or does it just not respond? Also, does this happen only on your iPhone or on other devices if you use Notee there?

Since you’ve already restarted, confirmed updates, force closed, and even re-added the app, here are a few additional steps we can try:

1. Check network connection: Sometimes connectivity issues can prevent the app from loading properly. Ensure you have a stable Wi-Fi or cellular connection.

2. Reset Network Settings: It can clear any potential conflicts affecting app connectivity without deleting your data. You can do this via Settings > General > Reset > Reset Network Settings. Just note you’ll need to re-enter Wi-Fi passwords afterward.

3. Check app permissions: Go to Settings > Privacy and ensure Notee has necessary permissions enabled, such as access to storage or notifications.

4. Verify iCloud sync (if used): If Notee syncs notes via iCloud, ensure sync is enabled at Settings > [your name] > iCloud > Notee (or Notes). Try toggling it off and back on to refresh syncing.

5. Check device storage: Low storage can cause apps to malfunction. You can see your available storage at Settings > General > iPhone Storage.

If these steps don’t help, it may be useful to look at any error logs or contact Notee’s support for potential compatibility issues with certain iOS versions.

Let me know how these go or if you see any different behaviors or messages. That will help me guide you further!
