How can I use the variable (.nextid) in the User Manager

I have an application with c# and when I open it it takes a lot of delay in load users, sessions and payment.
So I stored the users, sessions and payment in a local database for the application and I want when I open the application again it load only the latest new sessions.

When I use the command

mk.Send("/tool/user-manager/user/print");
mk.Send("?.nextid=*37B84CFD",true);

it does not give any data

and when i use the .id it load data

mk.Send("/tool/user-manager/user/print");
mk.Send("?.id=*37B84CFD",true);

Also use the command in terminal

/tool ​​user-manager user print where .nextid=*37B84CFD

it does not give any data

How can I do that

Is there a solution to this?

Solution? No?

What is .nextid? Is for v7?
I have never used it and if you know what it is for, please explain it to me.

If last user have .id=*37B84CFD

Try like this

/tool ​​user-manager user print where .id>*37B84CFD
