TeamViewer No Longer Savings partner ID's

TV12\Windows10

In the past, may go back 2 mos or so, TeamViewer  would save all the PARTNER ID's I had remotely connected with.  You would click in Partner ID Box and a drop down menu would display with all Partner ID's I had previously connected with.  Now I must ask the party I am connecting to to provide their Partner ID even though its been the same forever.

Is this a Software change?  Is there a setting I must select so that the Partner ID's are saved?
