Really strange. We have a general update policy for all our iPhones to "Install iOS/iPadOS Latest update". And i have tried creating a separate policy and group for just our iPhone 12 models and also to specifically "Install iOS/iPadOS 14.2.1". But the same message appears.

And one more thing i noticed is that the iPhone 12 model is recognized as just "iPhone" as model in both Endpoint Manager and the Company Portal app..

TomHolm We have noticed the same.

the iphone 12 is indeed mentioned as just iPhone.

also i have two variants of the issue. the iphone 12 devices that were already on 14.2 wont update to 14.2.1 with the notification that they fail to download.

i had one new iphone 12 that was still on 14.1 at the time 14.2.1 was released. and that one constantly started the update, but when it was time to install, it returned to the screen showing there was an update availible an i could click download and install again. this kept on going for a day and then it installed the 14.2.1 update.

i have checked the intune logging on the iphone 12 with the error, https://www.petervanderwoude.nl/post/quick-tip-intune-diagnostics-for-app-protection-policies-via-aboutintunehelp/ but the logging does not show anything usefull. at least not to me

  Yeah, the issue is still happening. Wonder if it will resolve itself when the next iOS update is released.

    Use iTunes, if you really need the update so badly.
    That is the only solution that worked for me.
