I wrote a test app to fetch cat images and display them in a user notification with a custom UNNotificationContentExtension. On my iPad Pro 9.7 and 12 devices, this works fine. The custom ui is displayed with the actions shown below. When I try this on an iPad 4, the custom ui does not appear but the actions do appear. All devices running 10.3.2.
The iPad 4's model number is MD511ZP/A which is a iPad Wi-Fi 4th Gen 32GB Black.
Any ideas on how to fix this?
