Answer 1

Have you set

"content-available": 1

in you backend APS payload?

Also need to make sure you have enabled background mode in your iOS App's info.plist file

<key>UIBackgroundModes</key>
<array>
    <string>processing</string>
    <string>remote-notification</string>
</array>

Answer 2

I spend a support ticket to get an answer to this problem.

It turns out that the documentation is not 100% "valid" for iOS 13 on this topic. The device decides whether to wake up or not. Although the documentation states a little different.

Apple's preferred way of implementation as a notification extension. After that, you have to adapt the payload to include "mutable-content".

I asked the support afterward if I should file a radar and they replied with "yes".
