IPad is Jailbroken

I don’t think your bank knows what they’re talking about. To jailbreak a person must have your iPad in their possession, a computer, probably know your Apple ID and knowledge of how to do it.

Long before your bank suggested it you would have noticed your iPad no longer operates like an iPad and you would have asked “What’s this strange app icon on my home screen.”

Jailbreaking is a forbidden topic on the Forum so just to get a fuller understanding of what it entails I recommend doing an internet search on the topic. There are plenty of YT videos on the topic.

I would contact the bank and ask them what is my iPad doing wrong to make you think it’s jailbroken. It may be something as simple as their app needs updating.

Also if yor iPad were jailbroken you would no longer have the latest IOS, you you have no IOS at all.

At the time of writing, iOS/iPadOS 27.0.1 are current.

Making the assumption that your iPad has not been jailbroken, start by removing the offending banking App from your iPad - and then perform a forced restart of the iPad prior to reinstalling the App from the App Store.

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

If the problem persists after performing the restart, it may be necessary to reset your iPad settings. While this reset will not cause any loss of data, as a precaution, it is always wise to ensure that you have a current iCloud or iTunes backup before performing the reset:

When you are happy to proceed, you can perform the reset from iPad settings:

Settings > General > Transfer or Reset iPad > Reset > Reset All Settings

If the problem still doesn’t clear, the next step is to reset the iPad to factory settings:

Otherwise, in this instance, you would be best advised to seek assistance directly from Bank - as the App may need to be updated for compatibility with iOS/iPadOS 27.x.

Guess: the installed banking app doesn’t support iOS 27, and the app is poking around where it probably shouldn’t, and is getting confused by iOS 27 changes.

If you’re on an iOS 27 beta, update to the released version of iOS 27.

Check for available banking app updates, too.

Then ask your bank if the app is supported on iOS 27 yet, and why the app is reporting a spurious error.

If you are running a beta version of iPadOS, you will get that message.

If your banking app has not been updated to recognize iPadOS 27, you will get that message.

It is possible if you are running a vpn, you could get various error messages.

If you're running a VPN then delete it from your device and see if that works.

iOS 26 can be jailbroken, but only under certain hardware. iOS 27 has no known jailbreak available.

In short, your bank doesn't know what they're talking about.
