Mount like a local disc is greyed out

I cant tick this option, even though my plan is professional. I have updated drive, signed in/out,stopped started program and rebooted. Why doesny my recognize my subscription?

Hi~ @Team_ikoiko,

To use the Local Disk function, you must check the Local Disk, Folder Mount option in the Addon item when you subscribe to Professional.
Addon can be added by accessing the RaiDrive homepage, moving to the Subscription tab, and clicking the Change button.
