Hi! I understand you’re having trouble logging into the Novo Banco app on your iPhone with iOS 18.6. I’d be happy to help you get this sorted out. To begin, could you tell me a bit more about what happens when you try to enter the app? For example:

- Do you see an error message? If yes, what does it say?
- Are you having trouble with your username, password, or perhaps device recognition?
- Is the app freezing, crashing, or simply not responding when you try to open it?

This info will help me guide you more precisely. Meanwhile, here are some common first steps you can try that often solve login problems:

1. Make sure your app is updated to the latest version from the App Store.
2. Check your internet connection—Wi-Fi or cellular data—to ensure it’s stable.
3. Try closing the app completely and reopening it (swipe up on the app from the app switcher).
4. Restart your iPhone, as this can clear minor glitches.

Once you tell me more about what you see, I can guide you through further steps like verifying your login credentials or checking app permissions. Does that sound good?
