    I am having the same message appear on a Unity iPad demo

    "This app may slow down your iPad."

    Is there a known cause for this. My app is a small test proof of concept and doesn't really have much to it besides some tutorial projects imported.

    I believe that warning appears when you run a 32-bit app on iOS 10. Are you using an old version of Unity? Something 4.6 or older, perhaps?

    If your app is indeed 32-bit, you will not be able to submit it to the app store without first making it 64-bit.

    This message makes me a bit angry. As it's a blatant lie, and a very developer-hostile move from Apple.

    I've got an old game that's very well optimised (60fps on iPhone 4 - it was C++/Marmalade, not Unity), sub-50MB installed. It hasn't been updated for a couple of years as it was *finished*, isn't a game-as-a-service, still runs well on modern devices, and I've moved on to other things. Compared to many modern games/apps it's super-efficient, really.

    (And in this case, it's not practical to update it as I no longer have a Marmalade license, and the Marmalade SDK is being discontinued very soon, and it was last built with a very old version so could be a painful update process for no real gain anyway...)

    Seems that you only get the message once, not on every launch of the app, at least.

    Just saw this warning on a new build of our game -- which does use IL2CPP, so it should be 64bit, right? We've submitted it successfully to the App Store within the past two months, so it must be 64bit. So why is this alert getting triggered?

    EDIT: Nevermind. Somehow the xcode build settings were on the non-64bit option.

    I'm surprised you managed to get a non-64bit build onto the store in recent months? - I thought 32bit-only apps were automatically rejected these days?

    No, somehow the build settings switched to non-64 in my last Unity build, but had been correct previously

    Restore does not apply here. This issue refers to 32-bit vs 64-bit builds

    That account is also spamming promotions for the same software in other posts. I reported that account.
