Received Something Went Wrong Message on MS Defender on an iPhone

MDW 5

When I try open the Alerts and History Bell on the MS Defender app on the iPhone, I receive Something Went Wrong message. Additionally, the following is also displayed: "We can't show alerts and history for this device, or notify you about threats on other devices."

I have signed out of MS Defender, deleted and reinstalled the app and still receiving the same message.

Any ideas on how to resolve this?

Your help is appreciated.

Thanks

Dear MDW,

I understand that the Alerts & History section in Microsoft Defender on your iPhone shows a “Something went wrong” message and cannot display alerts for this or your other devices. You have already signed out and reinstalled the app, but the same error continues.

Please try the options below and check whether the issue continues:

Update both Microsoft Defender in the App Store and iOS under Settings > General > Software Update.
Confirm that Defender is signed in with the personal Microsoft account connected to an active Microsoft 365 Personal or Family subscription.
Open Settings > Notifications > Defender, turn on Allow Notifications, then restart the iPhone. Defender needs notification permission to report blocked threats on iOS.
Temporarily switch from Wi-Fi to mobile data, or vice versa, and disable any third-party VPN or DNS-filtering app before testing again.

Please let me know how it goes after trying these steps, and I'll be glad to continue looking into it with you.

I followed all the steps you recommended and the same issue is still occurring. I have also deleted and reinstalled the app too.

Dear MDW, JoAnnCournoyer-4093

It appears this issue is affecting multiple users, and there is currently no publicly confirmed solution for the specific Alerts & History error. Since reinstalling and signing in again have not helped, please submit feedback with diagnostic data through the Defender app to bring the issue to the product team’s attention. Open Microsoft Defender > select your profile icon > then choose Help and Feedback > Send Feedback.

Please note that this is a user-to-user community forum. Moderators and contributors do not have access to Defender’s backend systems or individual account data, so we can only share suggestions based on available information and personal experience.

Please also keep both Microsoft Defender and iOS updated in case any improvements become available for this issue.

Thank you so much for your patience and your understanding!

Best regards.
