Hi there! Sorry to hear that the ONE@Work app isn’t working for you. I'd be happy to help get this sorted out. To start, could you please tell me a bit more about what’s happening? For example:

- Does the app fail to open, crash, or freeze?
- Are you seeing any error messages?
- Did this happen after an update or suddenly one day?
- Have you tried any steps on your own yet, like restarting the app or your iPhone?

These details will help me guide you through the best possible fix. Looking forward to your reply!

Fail to open

Thanks for letting me know the app fails to open. Let’s try some steps to get it working again on your iPhone with iOS 18.7.

1. Force Close and Reopen the App:
- Swipe up from the bottom of the screen and pause to open the app switcher.
- Find the ONE@Work app and swipe it up off the screen to close it completely.
- Tap the app icon to reopen it.

2. Restart Your iPhone:
Sometimes a fresh restart resolves temporary glitches. Hold the power button and slide to power off. After it turns off, hold the power button again to turn it on.

3. Check for Updates:
- Open the App Store, tap your profile icon at the top right, and scroll to see if the ONE@Work app has an update.
- If yes, update it as the latest version might fix bugs.

4. Reinstall the App:
- Press and hold the ONE@Work app icon until it jiggles, then tap the X or Remove App to delete it.
- Go back to the App Store and download the app again. Log in and see if it opens properly.

5. Check iOS Version Compatibility:
Since you are on iOS 18.7, the app should be compatible, but if possible, check the app description in the App Store to confirm the supported iOS versions.

If you have tried any of these already, please let me know which ones, and we can look into deeper settings or possible account/server issues.

Are you comfortable starting with these? I’ll guide you through each step as needed!
