We have a Pro subscription with 13 computers attached to it. We just recetly added the 13th machine, but the "User" section is now gone from the left side... but it was there when the 12th machine was added last year.
We only use 2 additional sub-user seats, one with access to 1 computer and the other for our tech with access to the majority of the others.
Where has the User screen gone in order to give our tech access to the new computer? Both sub-users still have access to their designated computers.
