Problems with iPad Pro M4 13 inch

We have an iOS/iPadOS (mixed use of UIKit/SwiftUI) app on the App Store since a couple of years.

Over the last month or so, we are receiving many user reports complaining about app freezing and behaving very bad generally. The common denominator for all of these users (~10) is that they are using iPad Pro M4, 13 inch, and they are on at least iPadOS 26.2 - some have updated to 26.2.1, 26.3 etc but the problems remain. Some of the users say that they were using our app normally, until the release of 26.2, or perhaps 26.2.1, from when the problems seem to have started.

Some report the problems that go away when they "use another WiFi", or when they hold the device in portrait mode (it seems that many complaints seem to suggest that the problem is in when holding the device in landscape). Other say the app works fine if they start it without network enabled, and after enabling network, continue in the app.

While we currently do not have an iPad Pro M4 13 inch to test with, we haven't been able to reproduce the problem on any other device.

We haven't heard of any similar problems from users of other devices.

While we have no idea what is causing these problems, my feeling is that there might be a possibility that there is some kind of problem with iPad Pro M4 and the recent iPadOS versions.

Just reaching out to see if anyone else have seen anything similar.
