Disable AD Sync

Hello,

I enabled AD Sync and it worked ok.
Now i want to disable it and it always shows as active in sophos central.

I uninstalled the app, rebooted the computer where it was installed, even oppened a support ticket for this problem.

Unfortunately nothing works, does anyone else have this problem?

I want to disable sync because when the users synced one of them is the administrator account, and that account does not have a computer, however it uses a licence in sophos central.
Now i want to delete the account so the licence warning dissapears but the system wont let me because it´s part of the administrators group.

Thanks for the help.
