Mobile keyboard issue: "Your organizations data cannot be pasted here" - Intune App Protection

I have an ongoing issue where I've setup an Intune app protection policy for unmanaged devices to restrict the ability to copy company data outside of company managed apps into personal apps.

Whilst this feature works in respect to managed apps and non-managed apps, there is a UI issue on both Android and iOS where the keyboard clipboard shows straight after you copy text in a managed app: "Your organizations data cannot be pasted here".

How do you stop this annoying popup that seems to relate to mobile keyboard clipboards?

It's an annoying issue as users think they can't copy/paste between work apps. We have to tell them every time that if they just press down on screen then press paste, it pastes correctly.

Example of our iOS policy is per below. Please help!
