Entra hybrid join and devices in dual state

Hello,

to test hybrid join, I created a lab that reproduces what we have as resources, like domain controller, notebooks and Microsoft 365 accounts and software; initially, we have all our notebooks registered as Entra registered because users have installed and configured the Office and Teams apps on their devices; with Connect agent in advanced mode, I then synced the various notebooks I had in the OUs and therefore obtained the various Entra hybrid joined devices; doing this way, I have the classic case of devices in dual state: I waited a few days as was suggested in the documentation, but nothing happened: in this case, how can I proceed?

read other posts and did some tests, for example deleting the Entra registered device: in this case by restarting the notebook, when I try to launch Teams or an Office app I am asked to enter the user, or the user is incorrect and I have to sign out from the app and then sign in; Could I have problems with Outlook and all the mail I have on my devices?
Is there any other solution?

Another thing I noticed is this: the Entra registered device still presents some data such as the Owner, the User principal name

which instead on the device in Hybrid join have as values, N/A and None respectively:

in these cases, the the first is seen as a personal device and therefore this data is there and the second is seen as Corporate?

Any suggestion is appreciated.
