    After updating an iPhone 7 to 10.1 this morning, I've noticed that all data in the Health and Activity apps is missing. Has anyone else noticed this? All I can find is a thread on the apple forums. I'm hoping it's a display issue rather than an indication of the data actually having been removed!

    Did you log in into your iCloud service after reboot?

    Yes, still logged in!

    From the apple support channels, they suggested that the most likely cause was data corruption. The issue persisted after restoring a backup too.

    Oh hell. I should hold still until next update. Losing health data is a pure bummer for me.

    The thread I found above suggests that a small number of people see this issue, but clearly it isn't pervasive otherwise I would have expected more of an outcry! Hopefully you wouldn't be one of the unlucky few..

    I'm going to try restoring to a slightly older backup, and if that doesn't work attempt reverting the software to the previous version and restoring the backup again. If the latter works it would convince me that it's a software issue with the new update. [Or, as Apple suggested, a software issue with the old software that has rendered the data unusable in the new version, even if it works in the old software. Unfortunately, from my understanding of their messages they'd still classify this as data corruption, resulting in loss of all health data]

    Just upgraded now and same issue happened to me (7+).
    After some search, I found someone say that if downgraded to 10.02 (or 10.03) , the health data will show just fine. Hence cannot be data corruption , right? (I'm so scared and frustrated right now)

    Yes, I saw that in the thread I mentioned in my first post. Haven't tried it yet, let me know if it gets it working again for you! If it does, I'm thinking that one option would be to export the data as XML, perform the upgrade, then re-import it using a third party app (perhaps something like that suggested in the link below?). Some information might be lost though, not sure whether apple watch activities would be preserved.

    I'm seeing the same thing on my 7+. Hopefully Apple will have a fix soon.

    Luckily I see this OP.
    I will see how long should I wait for the next version of iOS 10 to upgrade. Skip iOS 10.1 for now.

    I had issues like this after installing 10.1Beta3 and going back to 10.0.2. I thought there was an issue with my health database file as Apple indicated, but now I'm not so sure.

    I lost over a years worth of data. Started completely fresh. Not happy about it.

    Reverting to 10.0.3 and restoring the backup seems to put everything back to normal. To me that almost certainly indicates a bug in 10.1. I'll follow up with Apple, and hopefully they'll fix the problem!
