I have tested the BitLocker configuration profile with Autopilot and it seems successful, but it saying "Used Space Only" when I checked the status (refer image1). However I have deployed same policy to a device already enrolled, it will be fully encrypted the disks(refer image2).
at the same time I was seen "Silent enablement of BitLocker will encrypt used disk space only." on below Microsoft article, but again I was doubt since it will be doing without any issue for already enrolled device as per image2.
So I was wondering is there anything missed in my configurations.
