About android corporate owned dedicated device mode with app protection

Hi SebastiaanSmits,

This requirement was actually raised by the customer before. The customer used the Samsung tab for colleagues in the branch office to use. Although it is a company device, they hope to prevent attachments or files from being save on the tab by the user when receiving mail or reading files, and then transferred to other non company device.
Currently, we are testing whether it can be achieved,
"This setting is supported for Microsoft Excel, OneNote, PowerPoint, Word, and Edge. It may also be supported by third-party and LOB apps."
I am currently only able to successfully block download or save as function of app protection in the Corporate owned, fully managed user devices mode, while the Corporate owned dedicated device mode has been unable to do so. I am wondering if it is due to the lack of a work profile.
That's why I wonder if anyone has successfully blocked saving a file in Corporate owned dedicated device mode.
