Our tenant already updated to 2504, but there is no option in the APP to configure Screen capture, Genmoji and Writing tools.
This blog article states that the Screen capture blocking is for blocking it from Apple Intelligence.
On the other hand the iOS APP learn MS article states that it completely blocks screen capture (does not mention that it is only for Apple Intelligence).
Even the Intune Message Center post MC1025202 states that you can control and allow screen capture in managed app type app config policy (com.microsoft.intune.mam.screencapturecontrol=Disabled), but you should remove it now and configure it via APP.
Sorry, but it is really confusing you write Intune blog and Intune What's New articles relating to settings that are simply not available in Intune, and that those articles (this blog, MC post and learn article) contradict each other.
Please clarify if the APP screen capture setting is only for Apple Intelligence, or it is for completely blocking screen captures/sharing/mirroring.
