Norton 360 app crashes on iPhone causing need to reauthorize
I noticed that I have to authenticate and then reauthorize Norton 360 on my phone frequently. I have latest IOS and latest N360

Hello @TimInMn

It sounds like Norton 360 may be losing its activation state if it’s presenting the initial activation screen as though your iPhone were a new device.

A few questions that may help narrow it down:

• Does this happen every time you open Norton 360, or only occasionally?
• Does the app actually crash back to the Home Screen first, or does it simply open to the activation screen?
• Approximately how often does this occur?
• Did the behavior begin after updating to iOS 26.6 or after a recent Norton 360 app update?

If you haven’t already, I’d start with the following:

• Restart the iPhone.
• Confirm Norton 360 is updated to the latest version from the App Store.
• If the problem continues, uninstall Norton 360, restart the iPhone, reinstall the app, then sign in with your existing Norton account.

If the issue persists after a clean reinstall, I’d recommend contacting Norton Support so they can review your account and collect diagnostic logs if needed. If this is an emerging product issue, those reports can help Norton determine whether a broader investigation or engineering fix is warranted.

I haven’t seen reports to conclude this is a general issue with iOS 26.6 or the iPhone 17, so Norton may be helped knowing the answers to the questions above and whether other users begin reporting similar behavior.

If a clean reinstall doesn’t resolve the issue, I’d recommend contacting Norton Support so they can review your account and collect diagnostic logs. If this is an emerging product issue, those reports help Norton determine whether a broader investigation or engineering fix is needed.

I’m not aware of a definitive user-side fix for this issue. The standard troubleshooting steps are worth trying, but if the behavior persists, I’d recommend contacting Norton Support so they can document the case and collect logs. If multiple reports point to the same underlying issue, that information can help Norton determine whether an engineering investigation or product update is needed.
I’m not aware of Norton publicly identify a root cause or confirm this as a known product issue.

Multiple users have reported similar activation or reauthorization behavior on iOS 26. Some users have found that reinstalling the app or recreating the VPN profile temporarily resolves the issue, while others report that the problem returns. I haven’t seen a definitive user-side fix or an official Norton statement identifying the root cause, so persistent cases should be reported to Norton Support for investigation.
