The issue on iPadOS is you cannot close the compose dialog at all if you have set isModalInPresentation: The user has to force-close the whole app. And not setting isModalInPresentation isn't practical on iPadOS, as every unintentional touch outside the compose dialog closes the compose dialog. And it is way too easy to touch the region outside the compose dialog. In addition, every time the user closes the compose dialog this way, a new mail draft is added to the users mail account. With the "Close" button, you'll be given the option to save or delete the draft instead.

Unfortunately, this bug is still present in iPadOS 26.5.

Do you have now anything to share about this bug or its fix? Unfortunately, it is still present in iPadOS 26.5. :-( As this thread is actually about visionOS, the corresponding iPadOS thread is there: https://developer.apple.com/forums/thread/821300

@DTS Engineer: Unfortunately, this bug is still present in iPadOS 26.4.2. Do you have any updates you can share?

There already seems to be an internal ticket, see https://developer.apple.com/forums/thread/748447?answerId=881302022#881302022. Let us hope this bug will be fixed in iPadOS 26.4.1.

I've filed FB22313288.

Since iPadOS 26.4, I'm also missing the Cancel-Button on iPad. Is this a bug or intentional?

I can confirm, that the app's Apple ID and the direct link to the app doesn't change.

As iOS 18.2 has been released: Can anybody confirm, that the bug is fixed?

I do not see anything in the release notes for iOS 18.2 Beta 4 that mentions this bug at all.

Was your old iPad on iPadOS 16? Then you might experience the bug described in this thread.

@DTS Engineer Any update regarding iOS 18.2b2?

Feedback FB13296695.

Same issue here on iOS 16. Have you ever found a reason and/or solution?

I'm facing the same issue: The entitlement is available in the provisioning profiles for development and ad-hoc distribution, but not for App Store distribution, despite it is listed under "Enabled Capabilities". See this thread: https://developer.apple.com/forums/thread/721772
